Question

. A compound contains nitrogen and oxygen in the mole ratio of 1:1. Which of the

following could be the molecular mass of this compound?
14
16
40
30

Answer 1

30

Step-by-step explanation:

Given that;

the compound contains nitrogen and oxygen in the ratio 1:1;

We can say the compound is NO

Now,

Molecular mass of NO;

Molar mass of N = 14g/mol

Molar mass of O = 16g/mol

Molecular mass of NO = 14 + 16 = 30g/mol
