    35) which if any of the following species are in the greatest c in a 0.100 molar solution Hsub2SOsub4 in water?
    a) Hsub2SOsub4 molecules
    b) Hsub3O^+ ions
    c) HSOsub4^- ions
    d) SOsub4^2- ions
    e) all species are in equillibrium and thus the same concentration.

    36) at 20 degrees C the vapor pressure of toluene is 22mm Hg and that of benzene is 75 mm Hg. An ideal solution, equimolar in toluene and and benzene is prepared. And 20 degree C what is the mole fraction of benzene in the vapor in equilibrium with the solution?
