The freezing point of a cyclohexane sample is 6.20*C. A soltuion is prepared by dissolving 0.4660g of an unknown solute in 36.0g cyclohexane. The freezing point of the solution if 4.11*C. Calculate the molar mass of the unknown solute. Kf for cyclohexane is 20.0*Ckg/mole.

  • Chemistry - ,

    delta T = Kf*molality
    Solve for molality.

    molality = moles/kg solvent
    Solve for moles.

    moles = grams/molar mass
    Solve for molar mass.
