Answer 2

The atomic masses of N and H are 14 g/mol and 1 g/mol respectively. The molecular weight of ammonia is 14+3(1)=17 g/mol.

Convert unit from g to kg

17 g/mol×

1000 g

1 kg

=0.017 kg/mol

1 mole of ammonia weighs 0.017 kg and contains Avogadro's number ( 6.023×10

23

) of molecules.

Molecular mass of an ammonia molecule =

6.023 ×10

23

molecules/mol=

0.017 kg/mol

= 17 g/mol
