Concept Introduction : The ideal gas equation helps to calculate the pressure, volume, temperature of ideal gas as follows:
If a gas is collected over water, the total pressure always represents the sum of gas pressure and vapour pressure of water.
Hence;
Gas pressure = Total pressure - vapour pressure

Suppose you are performing
a gas-producing reaction to experimentally determine the molar volume of the gas.
MgCl₂ (aq) + H₂(g)
Mg(s) + 2 HCl(aq)
A sample of Mg produces 21.5 mL of H₂ gas. The gas is collected over water at an atmospheric pressure of 768.6 mm Hg at
22 °C, at which the vapor pressure of water is 19.8 mm Hg.
What is the experimental value for the molar volume of the hydrogen gas in L/mol?
Consider the reaction of ferrous sulfide with a dilute acid:
FeS(s) +2HCI(aq)¬H2S(g)+FeCl2(1)
