Density of a gas is found to be `5.46//dm^(3)` at `27^(@)C` at 2 bar pressure What will be its density at `STP` ? .

A

`6 g dm^(-3)`

B

`4 g dm^(-3)`

C

`5 g dm^(-3)`

D

`3 g dm^(-3)`

Text Solution

Verified by Experts

The correct Answer is:
D
According to the ideal gas law,
`pM = dRT`
or `(M)/(R ) = (dT)/(p)`
For the same gas, `dT//p` becomes a constant at a given `T` and `p`. Under different conditions of `T` and `p`, we have
`(d_(1)T_(1))/(p_(1)) = (d_(2)T_(2))/(p_(2))`
or `d_(2) = (d_(1)T_(1)p_(2))/(p_(1)T_(2)) = ((5.46 g dm^(-3))(27 + 273 K) (1 ba r))/((2 ba r)(273 K))`
` = 3 g dm^(-3)`
