The density of `CO_(2)` is `0.326 g dm^(-3)` at `27^(@)C` and `0.25` bar pressure. What is the density of the gas at `47^(@)C` keeping the pressure constant?

Explanation

From the available data :
`rho_(1) = 0.326 g dm^(-3) , T_(1) = 27+273 = 300 K`
`rho_(2) = ? , T_(2) = 47+273 = 320 K`.
We know that, `rho_(1)T_(1) = rho_(2)T_(2)`
or `rho_(2) = (rho_(1)T_(1))/(T_(2)) = ((0.326 g dm^(-3)) xx (300 K))/((320 K)) = 0.31 g dm^(-3)`
