Question

What is the volume $\left(lit\right)$ of oxygen required at STP to completely convert $1.5moles$ of sulphur into sulphurdioxide

• A. $11.2$
• B. $22.4$
• C. $33.6$
• D. $44.8$

Answer 1

The correct option is C $33.6$

$S+O_2\to S{O}_2$
one mole of any compound occupies $22.4$ $liter$ at S.T.P.
$\therefore$ 1.5 $mol$l of Sulphur produced $S{O}_2$=1.5 $mol$
so volume of gas =$1.5\times 22.4$ $liter$= 33.6 $liter$
