Density of a gas is found to be 4 gm//dm...

Density of a gas is found to be `4 gm//dm^(3)` at `27^(@)C` and 2 bar
pressure. It density at STP will be :

A

`1.80 gm//dm^(3)`

B

`2.22 gm//dm^(3)`

C

`3.10 gm//dm^(3)`

D

`1.65 gm//dm^(3)`

Text Solution

Verified by Experts

The correct Answer is:
B
Density of a gas in found ………….
`PM = dRT`
`(P_(1))/(d_(1)T_(1))= (P_(2))/(d_(2)T_(2)) implies (2)/(4xx300) = (1.01)/(d_(2)xx273)`
`d_(2)= (4xx300xx1.01)/(2xx273) = 2.22 gm//dm^(3)`
