How much ammonia must react with sulfuric acid to form 33 g of ammonium sulfate?

Ammonia reacts with sulfuric acid. This synthesizes the ammonium sulfate salt.

This reaction proceeds according to the following chemical reaction equation:

2NH3 + H2SO4 = (NH4) 2SO4;

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

For this purpose, we divide the weight of the substance by its molar (atomic) mass.

M (NH4) 2SO4 = (14 + 4) x 2 + 32 + 16 x 4 = 132 grams / mol;

The amount of ammonium sulfate will be:

N (NH4) 2SO4 = 33/132 = 0.25 mol;

To get this amount of salt, you need to take 2 times more ammonia.

Let’s find its volume. To do this, multiply the amount of substance by the volume of one mole of gas, which is 22.4 liters.

V NH3 = 0.5 x 22.4 = 11.2 liters;
