A solution is prepared by dissolving 25.0 g of glucose, C6H12O6, in 125 g of water at 25oC. (show work please)

Determine the freezing point of the solution.

    mols sucrose = grams/molar mass
    solve for mols.

    molality = m = mols/kg solvent
    solve for m

    dT = Kf*m
    solve for dT and subtract from 0.
