Determine the amount of ammonia that will be required to prepare 100 g of a 25% solution

The mass of ammonia in 100 grams of a 25% solution will be:

m NH3 = 100 x 0.25 = 25 grams;

Let’s find the molar mass of ammonia:

M NH3 = 14 + 1 x 3 = 17 grams / mol;

Let’s find the amount of the substance:

N NH3 = 25/17 = 1.47 mol;

Under normal conditions, one mole of ideal gas takes up a volume of 22.4 liters.

Let’s find the volume of ammonia:

V NH3 = 1.47 x 22.4 = 32.928 liters;
