Open in App

Solution

No. of mole of ${S O}_{2}$ in ${7.466 d m}^{3}$ at STP
At STP, V= $22.4 L$
$22.4 L$ of ${S O}_{2}$ contains $1$ mole of ${S O}_{2}$
$22.4 L ⟶ 1$ mole of ${S O}_{2}$
$L ⟶ \frac{1}{22.4}$ mole of ${S O}_{2}$
${7.466 d m}^{3} ⟶$ ? mole of ${S O}_{2}$
${1 d m}^{3} = 1 L 7.466 L ⟶ \frac{7.466}{22.4}$ mole of ${S O}_{2}$
$⟶ 0.33$ mole of ${S O}_{2}$
No. of mole of ${S O}_{2}$ in ${7.466 d m}^{3}$ at STP is $0.33$ mole
