    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.
