To calculate the percentage composition by mass of ammonia (NH₃), first determine the molar mass of ammonia by adding the atomic masses of its constituents: nitrogen (N) has a mass of about 14.01 g/mol, and hydrogen (H) has a mass of about 1.01 g/mol. Since ammonia contains one nitrogen atom and three hydrogen atoms, its molar mass is approximately 17.04 g/mol. The percentage composition by mass of nitrogen in ammonia is calculated as (mass of N / molar mass of NH₃) × 100, which gives about 82.24%, while the percentage composition of hydrogen is (mass of H / molar mass of NH₃) × 100, resulting in about 17.76%.
