# How much nitrogen and hydrogen will be required to produce 18 liters of ammonia?

We draw up the equation for obtaining ammonia: N2 + 3H2 = 2NH3.
Molar volume = 22.4L.
1) By dividing the volume by the molar volume, we obtain the amount of ammonia substance: 18 / 22.4 = 0.8 mol.
2) Determine the amount of nitrogen and hydrogen. According to the reaction equation, there is one mole of nitrogen for two moles of ammonia. This means that the amount of nitrogen substance is: 2 * 0.8 = 1.6 mol.
According to the reaction equation, there are three moles of hydrogen for two moles of ammonia. This means that the amount of hydrogen substance is: 2 * 0.8 / 3 = 0.5 mol.
3) The volume of nitrogen: 1.6 * 22.4 = 35.84 liters – answer 1.
4) The volume of hydrogen: 0.5 / 22.4 = 11.2 liters – answer 2.
