MCQ

Problem:

How much SO2 is produced by burning sulphur in 0.5 mol oxygen?
(a) 16 g
(b) 32 g
(c) 80 g
(d) 64 g


Solution:

The reaction is:
S and O subscript 2 yields S O subscript 2
1 mole of Oxygen gives 1 mole of SO2.
So, 0.5 mol of oxygen will give 0.5 mol of SO2.
Molar mass of SO2 = 64 g/mol
Mass of SO2 produced = 0.5 x 64 = 32 g
Correct option is (b).
