2NH3 ==> N2 + 3H2
When working with gases one can use volume directly as mols and not go through the conversion step of mols = L/22.4.
100 cc NH3 x (3 mols H2/2 mols NH3) = 100 x 3/2 = ? cc H2
what volume of hydrogen will be produced if 100cm3 of ammonia is completely decomposed at constant temperature and pressure.

p V = n R T
p/RT = n/V = constant here
n of H2/V of H2 = n of NH3/V of NH3
V of H2 = (n of H2/ n of NH3)100 cm^3
for every 2 mols of NH3 you get 3 mols of H2
so
n of H2/n of NH3 = 1.5
so
V = 1.5 * 100 = 150 cm^3
p/RT = n/V = constant here
n of H2/V of H2 = n of NH3/V of NH3
V of H2 = (n of H2/ n of NH3)100 cm^3
for every 2 mols of NH3 you get 3 mols of H2
so
n of H2/n of NH3 = 1.5
so
V = 1.5 * 100 = 150 cm^3
