Answer» The NUMBER of moles of methane is 163.2 =0.2.The pressure exerted by methane is P= VNRT = 9×10 −3 0.2×8.314×300 =5.54×10 4 Pa.The number of moles of CO 2 is 444.4 =0.1.The pressure exerted by CO 2 is P ′ = Vn ′ RT = 9×10 −3 0.1×8.314×300 =2.77×10 4 Pa.The total pressure is P+P ′ =5.54×10 4 Pa+2.77×10 4 Pa=8.31×10 4 Pa. |
