P=(n RT/V)=(0.20×0.0821×298/10)=0.49 atm

Q. $A$ $10 L$ flask contains a gaseous mixture of $CO$ and $C O_{2}$ at a total pressure of $2$ atm and $298 K$ . If $0.20$ mole of $CO$ is present, find its partial pressure.

$0.49$ atm

$1.51$ atm

$1$ atm

$2$ atm

$P = \frac{n RT}{V} = \frac{0.20 \times 0.0821 \times 298}{10} = 0.49 a t m$
