What is the volume (in litres) of oxygen required at STP to completely convert $1.5 \mathrm{~mol}$ of sulphur into sulphur dioxide?
- 11.2
- 22.4
- 33.6
- 44.8
Solution
$\mathrm{S}+\mathrm{O}_2 \longrightarrow \mathrm{SO}_2$
$32 \mathrm{~g} \quad 32 \mathrm{~g}$
1 mole $\quad 22.4 \mathrm{~L}$
1 mole of $S$ required volume of
$\mathrm{O}_2=22.4 \mathrm{~L}$
So, 1.5 mole of $S$ required volume of
$\mathrm{O}_2=22.4 \times 1.5=33.60 \mathrm{~L}$
