Calculate the mass of ammonia obtained by the interaction of caustic soda with 40g. ammonium nitrate.

This reaction proceeds according to the following chemical reaction equation:

NH4NO3 + NaOH = NH3 + NaNO3;

Let’s calculate the chemical amount of ammonium nitrate. For this purpose, we divide its weight by its molar mass.

M NH4NO3 = 14 + 4 + 14 + 16 x 3 = 80 grams / mol;

N NH4NO3 = 40/80 = 0.5 mol;

During the reaction, the same amount of ammonia will be released.

Let’s calculate its weight.

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

m NH3 = 0.5 x 17 = 8.5 grams;
