In this experiment, you will need to prepare 250.0 mL of 0.100 M KCl(aq) solution. Determine the mass in grams of potassium chloride required to prepare this solution. Type your numerical answer (no units) in the box below. Even though the number of significant figures is limited to three by the inputs, please report your answer to four significant figures.

Answers

Answer: The mass in grams of potassium chloride required to prepare this solution is 1.862 grams

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

[tex]Molarity=\frac{n\times 1000}{V_s}[/tex]

where,

n = moles of solute

[tex]V_s[/tex] = volume of solution in ml

moles of [tex]KCl[/tex] = [tex]\frac{\text {given mass}}{\text {Molar mass}}=\frac{xg}{74.5g/mol}[/tex]

Now put all the given values in the formula of molality, we get

[tex]0.100=\frac{x\times 1000}{74.5g/mol\times 250.0ml}[/tex]

[tex]x=1.862g[/tex]

Therefore, the mass in grams of potassium chloride required to prepare this solution is 1.862 grams

How many grams of water can be heated from 15.0 oC to 55oC using 4250.0 J.

Answers

Answer:

25.42 grams

Explanation:

The specific heat of water is 4.18 J/g •°C, so that means that it takes 4.18 joules of energy to raise one gram of water 1 °C.

Change in temp = 55 - 15 = 40°C

So we can calculate how much energy it would take to raise the temp of one gram of water by one degree using the following

(4.18 J/g•°C) * (40°C) * (1 gram) = 167.2 J

So if it takes 167.2 J of energy to raise on gram of water 40°C, we now we can calculate the amount of grams of water that can heated with 4250 J of energy

(4250 J) ÷ (167.2 J) = 25.42 grams of water can be heated from 15°C to 55°C

As the temperature in a sample of gas molecules decreases, which
of the other properties of the gas molecules could be caused to
increase or decrease? *
(Please help me)

Answers

Answer:

See Explanation

Explanation:

The kinetic energy of gas molecules is related to the temperature of the gas because temperature is a measure of the average kinetic energy of the molecules of a gas hence the lower the temperature of the gas the lower the average kinetic energy of the molecules of the gas.

The volume of a given mass of gas is directly proportional its absolute temperature(Charles's law). Hence, as the temperature of the gas gas decreases, the gas volume also decreases.

The number of gas molecules is totally independent of the temperature of the gas hence it stays the same.

As the temperature decreases, the number of collision of gas particles decreases as the kinetic energy of the gas particles decreases.

The pressure of a given mass of gas is related to the movement of gas particles. Hence, the lower the temperature the lower the pressure of the gas. Pressure and temperature are directly related hence pressure decreases as temperature decreases.

A gas has a volume of 6.00 liters at a temperature of 300 K and a pressure of 1.00 atm what is the volume of the gas in liters at a temperature of 600 K and a pressure of 3.00 atm

Answers

Answer:

V₂ = 4.00 L

Explanation:

Given that:

Volume (v1) = 6.00 L

Temperature (T1) = 300 K

Pressure (P1) = 1.00 atm

VOlume (V2) = unknown???

Temperature (T2) = 600 K

Pressure (P2) = 3.00 atm

Using combined gas law equation:

[tex]\dfrac{P_1V_1}{T_1}= \dfrac{P_2V_2}{T_2}[/tex]

[tex]\dfrac{1 \times 6}{300} = \dfrac{3 \times V_2}{600}[/tex]

[tex]\dfrac{1}{50} = \dfrac{1 \times V_2}{200}[/tex]

200 = 50V₂

V₂ = 200/50

V₂ = 4.00 L

While recording the crime scene, the photographer snapped a picture of his partner posing beside the famous victim's body. After printing the photo for his partner, he should just delete the image so nobody gets in trouble is false.

What is photographer?

Photographer is defined as a specialist who concentrates on the craft of shooting pictures with a digital or film camera. We can now describe the present, visualize the future, and visualize the history thanks to photography. The predecessor to the contemporary digital camera was the camera obscura. In the past, paintings were the most popular medium for capturing important historical events.

An approach known as "painting with light" is frequently used by seasoned photographers to expose image details in dim or near-dark lighting. By holding the shutter open for a few seconds or minutes while moving around the scene, the photographer can add light from sources like a flashlight or a flash from a separate camera.

The photographer's partner was photographed posing next to the body of the well-known victim as he documented the murder scene. It is erroneous to say that after printing the photo for his spouse, he should immediately erase it.

8. Calculate (H^+), (OH^-), pOH and the pH for a 0.00024 M solution of calcium hydroxide. Must show work!

Answers

Answer:

1. [H⁺] = 2.0×10¯¹¹ M

2. [OH¯] = 4.8×10¯⁴ M

3. pOH = 3.3

4. pH = 10.7

Explanation:

From the question given above, the following data were obtained obtained:

Molarity of Ca(OH)₂ = 0.00024 M

We'll begin by calculating the concentration of the hydroxide ion [OH¯]. This can be obtained as follow:

Ca(OH)₂ (aq) —> Ca²⁺ + 2OH¯

From the balanced equation above,

1 mole of Ca(OH)₂ produced 2 moles of OH¯.

Therefore, 0.00024 M Ca(OH)₂ will produce = 2 × 0.00024 = 4.8×10¯⁴ M OH¯

Thus, the concentration of the hydroxide ion [OH¯] is 4.8×10¯⁴ M

Next, we shall determine the pOH of the solution. This can be obtained as follow:

Concentration of the hydroxide ion [OH¯] = 4.8×10¯⁴ M

pOH =?

pOH = –Log [OH¯]

pOH = –Log 4.8×10¯⁴

pOH = 3.3

Next, we shall determine the pH of the solution. This can be obtained as follow:

pOH = 3.3

pH =?

pH + pOH = 14

pH + 3.3 = 14

Collect like terms

pH = 14 – 3.3

pH = 10.7

Finally, we shall determine the concentration of hydrogen ion [H⁺]. This can be obtained as follow:

pH = 10.7

Concentration of hydrogen ion [H⁺] =?

pH = –Log [H⁺]

10.7 = –Log [H⁺]

Divide both side by –1

–10.7 = Log [H⁺]

Take the antilog of –10.7

[H⁺] = Antilog (–10.7)

[H⁺] = 2.0×10¯¹¹ M

SUMMARY:

1. [H⁺] = 2.0×10¯¹¹ M

2. [OH¯] = 4.8×10¯⁴ M

3. pOH = 3.3

4. pH = 10.7

Answers

Answer:

1. The gas law used: Dalton's law of partial pressure.

2. Pressure of nitrogen = 331 mmHg

Explanation:

From the question given above, the following data were obtained:

Total pressure (Pₜ) = 592 mmHg

Pressure of Oxygen (Pₒ) = 261 mmHg

Pressure of nitrogen (Pₙ) =?

The pressure of nitrogen in the sample can be obtained by using the Dalton's law of partial pressure. This is illustrated below:

Pₜ = Pₒ + Pₙ

592 = 261 + Pₙ

Collect like terms

592 – 261 = Pₙ

331 = Pₙ

Pₙ = 331 mmHg

Therefore, the pressure of nitrogen in the sample is 331 mmHg
