Q. What is the volume (in litres) of oxygen required at STP to completely convert 1.5 moles of sulphur into sulphur dioxide?
A) 11.2
B) 22.4
C) 33.6
D) 44.8
Explanation
(c)
$\ \ S + O_{2} \rightarrow SO_{2}$
32 g 32 g
1 mole 22.4 L
1 mole of S required volume of
$O_{2} = 22.4\ L$
So, 1.5 mole of S required volume of
$O_{2} = 22.4 \times 1.5 = 33.60\ L$
