Calculate the volume of ammonia gas generated by the decomposition of 10.7 g of ammonium chloride.

Let’s calculate 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 = 10.7 / 53.5 = 0.2 mol;

The same amount of ammonia will be synthesized.

Let’s find its volume.

To do this, multiply the amount of substance by the standard volume of 1 mole of gas (which is 22.40 liters)

V NH3 = 0.2 x 22.4 = 4.48 liters;
