Expert Answer:

Mass of 1 mole of ammonia is molar mass of ammonia
Molar mass of ammonia = (atomic mass of N) + 3(atomic mass of H)
                               = 14 + (3×1)
                               = 17
Mass of 1 mole of ammonia is 17 g.
Hence, mass of 3 moles of ammonia = 3 × 17
                                                = 51 g
