Question

8 g of sulphur is completely burnt in large excess of oxygen. The volume in litres of sulphur dioxide formed at STP is

(a) 5.6

(b) 8.0

(c) 11.2

(d) 16.0

Answer 1

Correct option is (a) 5.6

S + O₂ → SO₂

Moles of SO₂ formed = \(\frac{1 \times 8}{32}\) = 0.25

Volume (STP) of SO₂ = 0.25 x 22.4 = 5.6 l
