Answer 2

hi friend,

here is your answer

Answer:

NH3

17.031 g/mol

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

NH2Cl

51.48 g/mol

To get the molar mass of the empirical formula, use the molar masses of its constituent atoms

molar mass empirical formula ×n = molar mass compound

14.0067 g/mol+2×1.00794 g/mol +35.453 g/mol

=51.48 g/mol

≈51.5 g/mol

= 51.48 g/mol
