C6H6 freezes at 5.5°C. At what temperature will a solution of 10 g of C4h10 in 200g of C6H6 freeze? The molal freezing point depression constant of C6H6 is 5.16°C/m?

  • chemistry -

    moles = gram/molar mass
    calculate moles C4H10.

    molality = moles/kg solvent.
    calculate molality.

    delta T = Kf*m
    calculate delta T and from there freezing point.
