What is the volume occupied by $16 \mathrm{~g}$ methane gas at STP?
  1. $1140 \mathrm{~cm}^3$
  2. $22400 \mathrm{~cm}^3$
  3. $214 \mathrm{~cm}^3$
  4. $12.4 \mathrm{~cm}^3$

Solution

Number of moles of methane $\left(\mathrm{CH}_4\right)=\frac{16}{16}=1$ Volume of 1 mole of gas at STP $=22.4 \mathrm{~L}$ $=22400 \mathrm{~cm}^3$
