The mass of `2.24 xx 10^(-3) m^(3)` of a gas is 4.4 g at 273.15 K and 101.325 kPa pressure. The gas may be

A

NO

B

`NO_(2)`

C

`C_(3) H_(8)`

D

`NH_(3)`

Text Solution

Verified by Experts

The correct Answer is:
C
m = 4.4 g , V = `2.24 xx 10^(-3) = 2.24 L`
T = 273.15 K
p = 101. 325kPa
= 101325Pa = 1 atm
pV = nRT or pV `= ( m )/( M ) RT `
or `M = ( m RT )/( pV )`
` = ( 4.4 xx 0.0821 xx 273.15)/( 1 xx 2.24 ) = 44.05 `
`:.` The gas is `C_(3) H_(8)`
