One litre of an unknown gas weighs 1.25 ...

One litre of an unknown gas weighs 1.25 g at N.T.P. which of the following gas pertains to the above data ?

A

`CO_(2)`

B

`NO_(2)`

C

`N_(2)`

D

`O_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
Mass of 1L of a gas at N.T.P. = 1.25 g mass of 22.4 L of the gas at N.T.P. `= 1.25 xx 22.4 = 28 g`
`:.` Gas is `N_(2)` (Mol mass of `N_(2) = 28`)
