A 0.750 g sample of an unknown substance is dissolved in 20.0 g of benzene, C6H6. The freezing point of the solution is 4.53 oC. Calculate the molar mass of the substance. The normal freezing point for benzene is 5.53 oC and Kf is 5.12 oC/m.

  • chemistry -

    delta T = Kf*m
    Calculate m
    m = mols/kg solvent.
    calculate moles.
    moles = grams/molar mass
    calculate molar mass.
