Question
Suppose you wish to make 0.879 l of 0.250 m silver nitrate by diluting a stock solution of 0.675 m silver nitrate. how many milliliters of the stock solution would you need to use?
Solution 1

Answer is: 325.5 mL of the stock solution.

c₁(AgNO₃) = 0.675 M.

V₂(AgNO₃) = 0.879 L.
c
₂(AgNO₃) = 0.250 M.
V
₁(AgNO₃) = ?
c
₁ - original concentration of the solution, before it gets diluted.
c
₂ - final concentration of the solution, after dilution.
V
₁ - volume to be diluted.
V
₂ - final volume after dilution.
c
₁ · V₁ = c₂ · V₂.
V
₁(AgNO₃) = c₂ · V₂ ÷ c₁.
V
₁(AgNO₃) = 0.250 M · 0.879 L ÷ 0.675 M.
V
₁(AgNO₃) = 0.325 L · 1000 mL = 325 mL.

Question
When copper reacts with silver nitrate according to the equation, the number of grams of copper required to produce 432 grams of silver is -?
Solution 1
Answer is: mass of copper is 127 grams.
Balanced chemical reaction: Cu(s) + 2AgNO₃(aq) → Cu(NO₃)₂(aq) + 2Ag(s).
m(Ag) = 432 g.
n(Ag) = m(Ag) ÷ M(Ag).
n(Ag) = 432 g ÷ 108 g/mol.
n(Ag) = 4 mol.
From chemical reaction: n(Ag) : n(Cu) = 2 : 1.
n(Cu) = 4 mol ÷ 2 = 2 mol.
m(Cu) = n(Cu) · M(Cu).
m(Cu) = 2 mol · 63.5 g/mol.
m(Cu) = 127 g.
Question
How does the total volume of gas particles compare to the volume of the space between gas particles?
Solution 1
There is more space between gas particles than the size of the particles.

Explanation:
This scenario can be understand by taking a very simple example. As we know that 1 mole of any gas at standard temperature and pressure occupy 22.4 liters of volume. Lets take Hydrogen gas and Oxygen gas, 1 mole of each gas will occupy same volume. Why it is so? Why same volume although Oxygen is 16 times more heavier? This is because the space between gas molecules is very large. Approximately the distance between gas molecules is 300 times greater than their own diameter from its neighbor molecules.
Question
Gas stoichiometry: what volume of oxygen at 25 degrees celsius and 1.04 atm is needed for the complete combustion of 5.53 grams of propane?
Solution 1
Answer is: volume of oxygen is 14.7 liters.
Balanced chemical reaction: C₃H₈ + 5O₂ → 3CO₂ + 4H₂O.
m(
C₃H₈-propane) = 5.53 g.
n(C₃H₈) = m(C₃H₈) ÷ M(C₃H₈).
n(C₃H₈) = 5.53 g ÷ 44.1 g/mol.
n(C₃H₈) = 0.125 mol.
From chemical reaction: n(C₃H₈) : n(O₂) = 1 : 5.
n(O₂) = 0.625 mol.
T = 25° = 298.15K.
p = 1.04 atm.
R = 0.08206 L·atm/mol·K.
Ideal gas law: p·V = n·R·T.
V(O₂) = n·R·T / p.
V(O₂) = 0.625 mol · 0.08206 L·atm/mol·K · 298.15 K / 1.04 atm.
V(O₂) = 14.7 L.

Question
A gas occupies 2240.0 l at 373 k. what are the volumes at standard temperature answers
Solution 1
Answer is: the volumes at standard temperature is 1639.46 L.
V₁(gas) = 2240.0 L.
T
₁(gas) = 373 K.
T
₂(gas) = 273 K, standard temperature.
V
₂(gas) = ?
Charles' Law:  The Temperature-Volume Law - the volume of a given amount of gas held at constant pressure is directly proportional to the Kelvin temperature:
V
₁/T₁ = V₂/T₂.
2240 L/373 K = V
₂/273 K.
V
₂ = 1639.46 L.
