Calculate the mass of ammonia that can be obtained by heating a mixture of 20 g of ammonium chloride and 20 g

Calculate the mass of ammonia that can be obtained by heating a mixture of 20 g of ammonium chloride and 20 g of calcium oxide, assuming that the mass fraction of the yield of ammonia is 98%.

This reaction proceeds according to the following chemical reaction equation:

2NH4Cl + CaO = 2NH3 + CaCl2;

Determine the chemical amount of ammonium chloride. For this purpose, we divide its weight by its molar mass.

M NH4Cl = 14 + 4 + 35.5 = 53.5 grams / mol;

The weight of ammonium chloride will be:

N NH4 Cl = 20 / 53.5 = 0.374 mol;

Let’s calculate the chemical amount of calcium oxide. To do this, we divide its weight by its molar mass.

M CaO = 40 + 16 = 56 grams / mol;

The amount of oxide will be:

N CaO = 20/56 = 0.3571 mol;

0.374 mol of ammonium chloride will react with 0.374 / 2 = 0.187 mol of calcium oxide. This will synthesize 0.374 mol of ammonia.

Let’s calculate its weight.

M NH3 = 14 + 3 = 17 grams / mol;

m NH3 = 0.374 x 17 = 6.358 grams;
