1 litre of a hydrocarbon weight as much ...

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

A

`C_(3)H_(8)`

B

`C_(2)H_(6)`

C

`C_(2)H_(4)`

D

`C_(3)H_(6)`

Text Solution

Verified by Experts

The correct Answer is:
A
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.
