What is the volume occupied by $32 \mathrm{~g}$ methane gas at STP?

What is the volume occupied by $32 \mathrm{~g}$ methane gas at STP?
  1. $56.0 \mathrm{dm}^3$
  2. $33.6 \mathrm{dm}^3$
  3. $22.4 \mathrm{dm}^3$
  4. $44.8 \mathrm{dm}^3$

Solution

Moles of $\mathrm{CH}_4=\frac{32}{16}=2$ Volume of occupied at STP $=2 \times 22.4 \mathrm{dm}^3$ $=44.8 \mathrm{dm}^3$
