Question

$ 1 $ litre of a hydrocarbon weighs as much as one litre of $ \mathrm{CO}_{2} $ at same $ \mathrm{P} $ and $ \mathrm{T} $. Then the molecular formula of the hydrocarbon is:, $ \mathrm{C}_{3} \mathrm{H}_{8} $, $ \mathrm{C}_{2} \mathrm{H}_{6} $, $ \mathrm{C}_{2} \mathrm{H}_{4} $, $ \mathrm{C}_{3} \mathrm{H}_{6} $

MARKS App · Accepted Answer

1 litre of a hydrocarbon weighs as much as one litre of CO 2 . Hence, 22 . 4 L of hydrocarbon will weigh as much as 22 . 4 L of CO 2 . 22 . 4 L of CO 2 weighs 12 + 16 2 = 44 g at NTP. Out of all hydrocarbons, C 3 H 8 only weighs 12 3 + 1 8 = 44 g .
