Problem

w_1 \text{ g}

of gas

A

and

w_2 \text{ g}

of gas

B

shows a mixture of molar mass 72. This

(w_1 + w_2) \text{ g}

mixture is placed in a container of volume

V

litre at 1 atm and

300 \text{ K}

. The density of mixture at these conditions is .....

\text{kg m}^{-3}

. (

R = 0.08 \text{ litre-atm K}^{-1} \text{ mol}^{-1}

)
