    A container is filled with 0.5 bar of He and 0.5 bar of Ar. A pinhole is then opened toallow the gases to effuse out of the container into a vacuum. After a period of time,the total pressure in the container falls from the initial value of 1.0 to 0.8 bar. Whatare the partial pressures of He and Ar remaining in the container?

    Hey, how could I go about this?

    was going to use rate(He)/rate(Ar) = sqrt ( M(Ar / M(He) )

    putting in the Mr of the elements I think gives some ratio of the effusion rate which I got as 3.16 but i'm not sure what to do with this
