The atomic mass of N is 14.01 g/mol, and the atomic mass of H is 1.008 g/mol. What is the molecular mass of NH3?

17.03 g/mol

15.018 g/mol

14.12 g/mol

45.054 g/mol

Option A = 17.03 g/mol

Explanation:

Given dа ta:

Atomic mass of nitrogen = 14.01 g/mol

Atomic mass of hydrogen = 1.008 g/mol

Molecular mass of NH₃ = ?

Solution:

Molecular mass of NH₃ = (14.01 g/mol * 1) + (1.008 g/mol * 3)

Molecular mass of NH₃ = 14.01 g/mol + 3.024 g/mol

Molecular mass of NH₃ = 17.03 g/mol

Ammonia consist of hydrogen and nitrogen both are nonmetals that's why ammonia is an covalent compound.
