1 litre of a hydrocarbon weight as much as one litre of `CO_(2)`. The moleecular formula of hydrocarbon is :-

Options

A. `C_(3)H_(8)`
B. `C_(2)H_(6)`
C. `C_(2)H_(4)`
D. `C_(3)H_(6)`

Answer

A

Explanation

mass of 1L `CO_(2)` = mass of 12 hydrocarbon
mass of `22.4L CO_(2)` =mass of `22.4L` hydrocarbon
44 g = mass of 1 mole hydrocarbon
mass of 1 mole hydrocarbon = 44 gm
Here `C_(3)H_(8)` has molar mass 44 gm.
