  1. b. mols C6H14O6 = grams/molar mass.
    Substitute mols into
    molality = mols/kg solvent and solve for m, then substitute m into
    delta T = Kb*m, solve for delta T and add to the normal boiling point for H2O.

    c. Use calculation for mols and molality from above and substitute into
    delta T = Kf*m and solve for delta T and subtract from normal freezing point of H2O.

    a. Psoln = XH2O*PoH2O
    where XH2O = mols H2O/total mols.
