Question

Molecular mass of Nitrogen is $28$. Its atomic mass is $14$. Find the atomicity of Nitrogen.

• A. 1
• B. 2
• C. 4
• D. 8

Answer 1

The correct option is B 2

$\text{Atomicity}=\frac{\text{Molecular mass}}{\text{Atomic mass}}=\frac{\text{28}}{\text{14}}=\text{2}$

One molecule of nitrogen has two atoms.
