At –11.0 °C (a common temperature for household freezers), what is the maximum mass of aspartame (C14H18N2O5) you can add to 1.50 kg of pure water and still have the solution freeze? Assume that aspartame is a molecular solid and does not ionize when it dissolves in water. Kf of water is 1.86 degree c/m.

  • Chemistry -

    delta T = Kf*m
    Substitute and solve for m

    m = mols/kg solvent
    Substitute and solve for mols.

    mols = grams/molar mass.
    Substitute and solve for grams.
