Question

Calculate mass of 1 molecules of ammonia

Answer 1

Answer:

Simply ot's 17g

for detail check the explanation

Explanation:

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 g1 kg=0.017 kg/mol

1 mole of ammonia weighs 0.017 kg and contains Avogadro's number ( 6.023×1023 ) of molecules.

Molecular mass of an ammonia molecule =6.023 ×1023 molecules/mol0.017 kg/mol=2.82×10−26 kg

mark me brainlest plz
