A containing vessel holds a gaseous mixture of nitrogen and butane. Thepressure in the vessel at 126.9 Cis 3.0 atm. At 0 C, the butane completelycondenses and the pressure drops to 1.0 atm. Calculate the mole fraction of nitrogenin the original gaseous mixture.

Answers

A vessel that contains a mixture of nitrogen and butane has a pressure of 3.0 atm at 126.9 °C and a pressure of 1.0 atm at 0 °C. The mole fraction of nitrogen in the mixture is 0.33.

A vessel contains a gaseous mixture of nitrogen and butane. At 126.9 °C (400.1 K) the pressure is due to the mixture is 3.0 atm.

We can calculate the total number of moles using the ideal gas equation.

[tex]P \times V = n \times R \times T\\\\n = \frac{P \times V}{R \times T} = \frac{3.0 atm \times V}{0.082 atm.L/mol.K \times 400.1 K} = 0.091 mol/L \times V[/tex]

At 0 °C (273.15 K), the pressure due to the gaseous nitrogen is 1.0 atm.

We can calculate the moles of nitrogen using the ideal gas equation.

[tex]P \times V = n \times R \times T\\\\n = \frac{P \times V}{R \times T} = \frac{1.0 atm \times V}{0.082 atm.L/mol.K \times 400.1 K} = 0.030 mol/L \times V[/tex]

The mole fraction of nitrogen in the mixture is:

[tex]X(N_2) = \frac{0.030 mol/L \times V}{0.091 mol/L \times V} = 0.33[/tex]

A vessel that contains a mixture of nitrogen and butane has a pressure of 3.0 atm at 126.9 °C and a pressure of 1.0 atm at 0 °C. The mole fraction of nitrogen in the mixture is 0.33.

Under an O2(g) pressure of 1.00 atm, 28.31 mL of O2(g) dissolves in 1.00 L H2O at 25 °C. What will be the molarity of O2 in the saturated solution at 25 °C when the O2 pressure is 4.47 atm? Assume that the solution volume remains at 1.00 L.

Answers

In the first case, the molarity of oxygen gas is 0.0012 mol/L. In the second case, the molarity of oxygen gas is 0.0052 mol/L .

We have to obtain the number of moles of oxygen as follows;

P = 1.00 atm

V = 28.31 mL or 0.02831 L

n = ?

R = 0.082 atm LK-1mol-1

T = 25 °C + 273 = 298 K

n = PV/RT

n=  1.00 atm × 0.02831 L/ 0.082 atm LK-1mol-1 ×  298 K

n = 0.0012 moles

Molarity = Number of moles/Volume = 0.0012 moles/1.00 L =  0.0012 mol/L

For the second case;

P = 4.47 atm

V = 28.31 mL or 0.02831 L

n = ?

R =  0.082 atm LK-1mol-1

T = 25 °C + 273 = 298 K

n = PV/RT

n = 4.47 atm ×  0.02831 L/0.082 atm LK-1mol-1 × 298 K

n = 0.1265/24.436

n = 0.0052 moles

Molarity of oxygen = 0.0052 moles/1.00 L = 0.0052 mol/L

The partial pressure of CO2 gas in a bottle of carbonated water is 4.60 atm at 25 ºC. How much CO2 gas (in g) will be released from 1.1 L of the carbonated water when the partial pressure of CO2 is lowered to 1.28 atm? At 25 ºC, the Henry’s law constant for CO2 dissolved in water is 1.65 x 103 atm, and the density of water is 1.0 g/cm3.

Answers

If the partial pressure of CO₂ in a bottle of carbonated water decreases from 4.60 atm to 1.28 atm, the mass of CO₂ released is 0.265 g.

The partial pressure of CO₂ gas in a bottle of carbonated water is 4.60 atm at 25 ºC. We can calculate the concentration of CO₂ using Henry's law.

[tex]C = k \times P = \frac{1.65 \times 10^{-3} M }{atm} \times 4.60 atm = 7.59 \times 10^{-3} M[/tex]

We can calculate the mass of CO₂ in 1.1 L considering its molar mass is 44.01 g/mol.

[tex]\frac{7.59 \times 10^{-3} mol}{L} \times 1.1 L \times \frac{44.01 g}{mol} = 0.367 g[/tex]

Now, we will repeat the same procedure for a partial pressure of 1.28 atm.

[tex]C = k \times P = \frac{1.65 \times 10^{-3} M }{atm} \times 1.28 atm = 2.11 \times 10^{-3} M[/tex]

[tex]\frac{2.11 \times 10^{-3} mol}{L} \times 1.1 L \times \frac{44.01 g}{mol} = 0.102 g[/tex]

The mass of CO₂ released will be equal to the difference in the masses at the different pressures.

[tex]m = 0.367 g - 0.102 g = 0.265 g[/tex]

How many atoms can be found in a sample of 75g of silicon

Answers

7.505x1022 maybe? I forget.

Answer:

[tex]\boxed {\boxed {\sf 1.6 \times 10^{24} \ atoms \ Si}}[/tex]

Explanation:

We are asked to find how many atoms are in a sample of 75 grams of silicon.

1. Convert Grams to Moles

First, we must convert grams to moles using the molar mass. This is the mass of 1 mole of a substance. The molar mass is found on the Periodic Table because it is equal to the atomic mass, but the units are grams per mole instead of atomic mass units.

Look up the molar mass of silicon.

Si: 28.085 g/mol

We convert using dimensional analysis, so we must set up a conversion factor.

[tex]\frac {28.085 \ g \ Si}{1 \ mol \ Si}[/tex]

We are converting 75 grams of silicon to moles, so we multiply by this value.

[tex]75 \ g \ Si*\frac {28.085 \ g \ Si}{1 \ mol \ Si}[/tex]

Flip the conversion factor so the units of grams of silicon cancel.

[tex]75 \ g \ Si*\frac {1 \ mol \ Si}{28.085 \ g \ Si}[/tex]

[tex]75 *\frac {1 \ mol \ Si}{28.085 }[/tex]

[tex]\frac {75}{28.085} \ mol \ Si[/tex]

[tex]2.670464661 \ mol \ Si[/tex]

2. Convert Moles to Atoms

Next, we convert moles to atoms using Avogadro's Number, or 6.022 ×10²³. This is the number of particles (atoms, molecules, formula units, etc.) in 1 mole of a substance. In this problem, the particles are atoms of silicon.

Set up another conversion factor, this time with Avogadro's Number.

[tex]\frac {6.022 \times 10^{23} \ atoms \ Si}{1 \ mol \ Si}[/tex]

Multiply by the number of moles we found.

[tex]2.670464661 \ mol \ Si*\frac {6.022 \times 10^{23} \ atoms \ Si}{1 \ mol \ Si}[/tex]

The units of moles of silicon cancel.

[tex]2.670464661 *\frac {6.022 \times 10^{23} \ atoms \ Si}{1 }[/tex]

[tex]2.670464661 * {6.022 \times 10^{23} \ atoms \ Si}[/tex]

[tex]1.60815382 \times 10^{24} \ atoms \ Si[/tex]

The original value of grams (75) has 2 significant figures, so our answer must have the same. For the number we found, that is the tenths place. The 0 in the hundredths place tells us to leave the 6 in the tenths place.

[tex]1.6 \times 10^{24} \ atoms \ Si[/tex]

Answer: Change in speed = 11 m/sTime taken = 3.4sHence, acceleration = (11/3.4) m/s² = 3.235 m/s²

Explanation:

(winks and runs off)

Acceleration is 3.235 m/s² when Usain Bolt went from 0.0 to 11.0 m/s in 3.4 seconds.

What is acceleration?

Acceleration is defined as a rate at which the velocity changes with time with respect to both speed and direction.An object is said to be accelerated if it's speeds up r slows down.

Motion along a circle is always accelerated even when speed is constant it's direction is continuously changing.Acceleration is a vector quantity as it has both magnitude as well as direction.The magnitude of acceleration is described by Newton's second law of motion.

Formula of acceleration is change in speed /time.Substituting the given values in the given formula,(11.0-0.0)/3.4=3.235 m/s².

Thus, the acceleration  is 3.235 m/s² when Usain Bolt went from 0.0 to 11.0 m/s in 3.4 seconds.

The molecules of the two gases will have the same kinetic energy at room temperature.

The average kinetic energy of gaseous molecules can be calculated using the formula:

Kinetic Energy = 3/2RT, where R = constant and T = temperature in Kelvin

If you use 0.200 M K I O 3 as the titrant, what concentration of I O 3 − (in M) do you predict will be needed to start precipitation in a 0.229 M solution of Z n ( N O 3 ) 2 ?

Answers

The predicted concentration of IO₃⁻ needed to start the precipitation titration is 1.703 × 10⁻⁷ M

The dissociation of zinc (II) iodate can be expressed as:

[tex]\mathbf{Zn (IO_3)_2 \to Zn^{2+} + 2IO_3^-}[/tex]

Given that the solubility product constant Ksp value = 3.9 × 10⁻⁶

For the above dissociation,

[tex]\mathbf{Ksp = [Zn^{2+ }] [IO_3^-]^2}[/tex]

Since [tex]\mathbf{ [Zn^{2+ }] = [Zn(NO_3)_2] = 0.229 \ M}[/tex]

[tex]\mathbf{3.9\times 10^{-8} =(0.229) \times [IO_3^-]^2}[/tex]

[tex]\mathbf{ [IO_3^-]^2 = \dfrac{3.9\times 10^{-8} }{(0.229)}}[/tex]

[tex]\mathbf{ [IO_3^-]^2 = 1.703 \times 10^{-7} \ M}[/tex]

Therefore, we can conclude that the initial predicted concentration of IO₃⁻ needed to start the precipitation titration is 1.703 × 10⁻⁷ M
