Question

A flask contains methane, chlorine, and carbon monoxide gases. The partial pressures of each are 0.215 atm, 50 torr, and 0.826 respectively. What is the total pressure in the flask?

Answer 1

`P_("total")=1.11atm`

Explanation:

According to Raoul's law of partial pressure, the total pressure of a mixture of gases is equal to the sum of the partial pressure of the individual gases"

`P_("total")=P_1+P_2+P_3+...`

Therefore, the total pressure of this mixture would be:

`P_("total")=P_(CH_4)+P_(Cl_2)+P_(CO)`

`=>P_("total")=0.215atm+50cancel("torr")xx(1atm)/(760cancel("torr"))+0.826atm=1.11atm`
