Question
When burnt in air, 14.0 g mixture of carbon and sulphur gives a mixture of CO2 and SO2 in the volume ratio of 2: 1, the volume being measured at the same conditions of temperature and pressure. Moles of carbon in the mixture is
Options
A.0.25
B.0.40
C.0.5
D.0.75
Solution
2a × 12 + a × 32 = 14 ⇒ Moles of carbon = 2a = 0.5
