Number of moles SO2 :
1 mol SO2 -------- 22.4 L ( at STP )
? mol SO2 --------- 3.42 L
1 x 3.42 / 22.4 => 0.152 moles of SO2
Therefore:
Molar mass SO2 => <span>64.066 g/mol
</span>
1 mole SO2 ---------- <span>64.066 g
</span>0.152 moles SO2 ---- ( Mass of SO2)
Mass of SO2 = 0.152 x 64.066 / 1
Mass of SO2 =
9.738 g
