#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#
