4.4 g of a gas at STP occupies a volume of 2.24 L. The gas can be :

A

`O_(2)`

B

CO

C

`NO_(2)`

D

`CO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
PV=nRT `" "PV=(m)/(M)RT`
`:.M=(mxxRxxT)/(PV)`
Mol.Wt. = `(Wt.xxRT)/(PV)`
M=`(4.4xx0.082xx273)/(1xx2.24)=44 g`
`:.` Gas is `CO_(2)`
