Stoichiometry w/Volume

Liquids and gas are most often measured by volume not by weight. We can use the density of a liquid or gas to convert a volume to a mass. Then that mass can be used in normal stoichiometric calculations. If we need the answer to be a volume, we can use the density to convert from a mass to a volume to satisfy the problem.

4 NH3 + 6 NO → 5N2 + 6 H2O How many liters of N2 gas can be made from 1.02 L NH3 gas according to the following equation? (DN2=1.251 g/L, DNH3=0.759 g/L)

2 HgO → 2Hg + O2 What volume of O2 and Hg can be produced from the decomposition of 23.01 g HgO according to the following equation? (DHg=7.6g/mL, DO2=1.43g/L)

If any gas is measured at STP (standard temperature and pressure) then 1mol = 22.41L We can use that conversion factor

N2 + 3H2 → 2NH3 How many moles of nitrogen gas is needed to react with 44.8 liters of hydrogen gas to produce ammonia gas? @STP

N2 + 3H2 → 2NH3 How many grams of ammonia are produced when 89.6 liters of hydrogen are used in the above reaction?
