What is matter?
Matter can be defined as anything that has mass and can occupy space.
Thus, any physical object or substance that is found on planet Earth is typically composed of matter.
The three (3) states of matter:
Since all matter are made up of atoms, they have a property of existing in three (3) distinct states and these include;

2. Strain
3. Elasticity
4. Boiling point
5. Surface tension
6. Vapor pressure

what volume will 28.0 g of O2 occupy at STP?
Answers
Considering the definition of STP conditions, 28 grams of O₂ will ocupy at STP 19.6 L.
The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.
On the other side, the molar mass of substance is a property defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.
In this case, you have 28 g of O₂. The molar mass es 32 [tex]\frac{g}{mole}[/tex]
Next, you can apply the following rule of three: if 32 grams of the compound are contained in 1 mole, 28 grams are contained in how many moles?
[tex]number of moles=\frac{28 gramsx1 mole}{32 grams}[/tex]
number of moles= 0.875 moles
Now, you can apply the following rule of three: if by definition of STP conditions 1 mole of O₂ occupies a volume of 22.4 liters, 0.875 moles occupies how much volume?
[tex]volume=\frac{0.875 molesx22.4 L}{1 mole}[/tex]
volume= 19.6 L
Finally, 28 grams of O₂ will ocupy at STP 19.6 L.

How many grams of solute are needed to order to prepare 100.00 mL of a 0.1000 M solution of a compound with a molecular weight of 350.0 g/mol
Answers
Answer:
i got 35 but i am as lost as you are so don't really take my answer as a trusted answer
The grams of solute are required.
The mass of solute is 3.5 g
c = Molarity = 0.1 M
M = Molar mass = 350 g/mol
V = Volume of solution = 100 mL = 0.1 L
n = Number of moles
m = Mass of solute
Molarity is given by
[tex]c=\dfrac{n}{V}\\\Rightarrow n=cV\\\Rightarrow n=0.1\times 0.1\\\Rightarrow n=0.01\ \text{moles}[/tex]
Molar mass is given by

Plant cells and animal cells are both eukaryotic cells. They both have a nucleus, Golgi complex, endoplasmic reticulum, ribosomes, mitochondria, cytoskeleton and cell membrane. Only plants cells have a vacuole, cell wall and chloroplast, while animal cells have cilia, centrioles and lysosomes which plant cells don't usually have. Because of their cell walls plant cells are in rigid rectangular shapes while animal cells have looser round shapes. The main difference in their functions is that animals don't produce their own food while plan cells do.

Answers
The molality of the solution is 1.4 moles per kilogram (molal).
The molality of the solution is equal to the number of moles of sugar (solute) divided by the number of kilograms of water (solvent). Hence, the molality is determined below:
[tex]m = \frac{3.5\,mol}{2.5\,kg}[/tex]
[tex]m = 1.4\,\frac{mol}{kg}[/tex]

How do you know how to order an empirical formula?
Answers
Answer:
Start with the number of grams of each element, given in the problem. the mass of each element = the percent given. Convert the mass of each element to moles using the molar mass from the periodic table. Divide each mole value by the smallest number of moles calculated.
Solving Empirical Formula Problems There are two common types of empirical formula problems. Luckily, the steps to solve either are almost exactly the same. Example #1: Given mass % of elements in a compound.
A compound was found to contain 32.65% Sulfur, 65.3% Oxygen and 2.04% Hydrogen. What is the empirical formula of the compound?
1) The first step in this problem is to change the % to grams.
32.65%→32.65g of S
65.3%→65.3g of O
2.04%→2.04g of H
2) Next divide all the given masses by their molar mass.
32.65g of S/ 32gm-1 = 1.0203 moles of S
65.3g of O/ 16gm-1 = 4.08 moles of O
2.04g of H/ 1.008gm-1 = 2.024 moles of H
3) Then, pick the smallest answer in moles from the previous step and divide all the answers by that. Remember that if you calculate a number that is x0.9 round to the nearest whole number
1.0203 moles of S/ 1.0203 = 1
4.08 moles of O/1.0203 = 3.998 ≈ 4
2.024 moles of H/1.0203 = 1.984 ≈ 2
4) Lastly, the coefficients calculated in the previous step will become the subscripts in the chemical formula.
S = 1
O = 4
H = 2
H2SO4
Example#2: Given the mass of a reactant before a chemical reaction and the mass of a product after a reaction.
When 0.273g of Mg is heated in a Nitrogen (N2) environment a chemical reaction occurs. The product of the reaction is 0.378g . Calculate the empirical formula.
1) In any empirical formula problem you must first find the mass % of the elements in the compound. Since the total mass of the final product was 0.378 we find that:
0.378g total-0.273g magnesium = 0.105g nitrogen
0.105g nitrogen/0.378g total (100) = 27.77%
0.273g magnesium/0.378g total (100) =72.23%
2) Then change the % to grams
27.77%→27.77g of N
72.23%→72.23g of Mg
3) Next, divide all the masses by their respective molar masses.
27.77g/14gm-1 = 1.98 moles N
72.23g/24.31gm-1 = 2.97 moles Mg
