A solution of 0.2113 g of water dissolved in 25.0 g of a solvent freezes at 11.5 °C below the freezing point of the solvent. What is Kf for this solvent?

  • chemistry -

    moles H2O = 0.2113/molar mass H2O.
    Solve for moles.
    molality = moles H2O/kg solvent.
    Solve for molality.
    delta T = Kf*m
    solve for Kf.
