Answer:
17.03052 g/mol
Explanation:
Ammonia formula is given as NH3.
To estimate the molar mass of any compound, we have to add up the molar masses of every atom of the given compound. Ammonia comprises of one nitrogen atom and three hydrogen atoms.
So the molar mass of ammonia is
N: 14.0067 g/mol
H: 1.00794 g/mol
The molar mass of ammonia will thus be
14.0067 g/mol +3× 1.00794 g/mol =17.03052 g/mol
