Calculate the freezing point of the following solutions, assuming complete dissociation.3.7% KCL by mass (in water)

  • Chemistry - ,

    3.7% KCl = 3.7 g KCl/100 g soln =
    3.7 g KCl/(3.7 g KCl + 96.3 g H2O) =
    Convert 3.7 g KCl to moles. moles = grams/molar mass

    Then molality = moles/kg solvent.

    delta T = i*kf*m
    i = 2, kf you know and m from above.
