Lawrence Bernard · Answer 1

The molar mass is the sum of the mass of all the atoms of a particular molecule.

The unit of molar mass is grams per mole.

The atomic mass of H = 1.00

The atomic mass of N = 14.00

The molar mass of ammonia = atomic mass of N + 3 x (atomic mass of H)

= 14.00 + 3 x (1.00) = 17.00

Therefore the molar mass of ammonia is 17g/mol

The correct answer is 17g/mol.
