Question

Find the volume occupied by $30\text{g}$ of neon gas at STP.

• A. $33.6\text{L}$
• B. $22.4\text{L}$
• C. $24.7\text{L}$
• D. $22.7\text{L}$

Answer 1

The correct option is A $33.6\text{L}$

Molar mass of neon gas = $20\text{g/mol}$
1 mole i.e.,$20\text{g}$ of neon gas occupies $22.4\text{L}$
$30\text{g}$ of neon gas will occupy $\frac{22.4}{20}\times 30=33.6\text{L}$
