Q5 / 160 · AP EAMCET 2003 · Chemistry

What is the volume (in litres) of oxygen required at STP to completely convert $1.5 \mathrm{~mol}$ of sulphur into sulphur dioxide?

  • A
    11.2
  • B
    22.4
  • Correct answer
    C
    33.6
  • D
    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 $\mathrm{O}_2=22.4 \times 1.5=33.60 \mathrm{~L}$

Hence, the correct answer is option: 'C'.
