A gas having molecular mass `84.5 g mol^(-1)` enclosed in a flask at `27^(@)C` has a pressure of `1.5 "bar"`. Calculate the density of the gas under the same conditions.

Answer

`5.09 g L^(-1)`

Explanation

Density of gas `(rho) = (MP)/(RT) , M = 84.5 g mol^(-1), P = 1.5 "bar", R = 0.083 L "bar" K^(-1) mol^(-1), T = 300 K`
`:. rho = ((84.5 g mol^(-1)) xx (1.5 "bar"))/((0.083 L "bar" K^(-1) mol^(-1)) xx (300 K)) = 5.09 g L^(-1)`
