0.015 moles of a compound are dissolved in 18 fl. oz. of water. At what temperature will the solution begin to freeze? The density of water is 1.00g/mL

  • AP Chemistry -

    Convert 18 fl oz to grams and to kg. 1 oz = 28.35 grams.

    molality = mols/kg solvent
    Solve for molality.

    Then delta T = Kf*m
    You know Kf and m, solve for delta T, then subtract from zero C to find the new freezing point.
