# 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?

${P}_{\text{total}} = 1.11 a t m$

#### 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"

${P}_{\text{total}} = {P}_{1} + {P}_{2} + {P}_{3} + \ldots$

Therefore, the total pressure of this mixture would be:

${P}_{\text{total}} = {P}_{C {H}_{4}} + {P}_{C {l}_{2}} + {P}_{C O}$

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