0.0224 L

Explanation:

We have,

$28 m g = 0.028 g$ $28mg=0.028g$

We know that, at ntp 22.4 L of gases have mass equivalent to their molar mass.

Molar mass of N2 gas $= 2 \cdot 14 = 28 g$ $= 2*14=28g$

Therefore 28g of N2 has a volume of 22.4 L

This implies that 0.028g of N2 has a volume $= \frac{22.4}{28} \cdot 0.028$ $=22.4/28 * 0.028$
$= \frac{22.4}{28} \cdot \frac{28}{1000} = \frac{22.4}{1000} = 0.0224 L$ $=22.4/28 * 28/1000 =22.4/1000 =0.0224 L$
