31.78 grams

25.55%

Explanation:

The balanced reaction for ammonium chloride with calcium oxide will be:

2NH4Cl + Ca (OH) 2 - --> CaCl2 + 2NH3 + 2H2O

The molecular weight for ammonium chloride (NH4Cl) is 53.49g/mol, while the molecular weight for ammonium (NH3) is 17g/mol. The number of theoretical yield of ammonia from 100g of ammonium chloride will be:

100g / (53.49g/mol) * 2/2 * 17g/mol = 31.78 grams

If the actual yield is 8.12g, the percent yield will be: 8.12g/31.78g * 100% = 25.55%
