A 2.97 g sample of a molecular compound
is dissolved in 103 g of tetrachloromethane
(carbon tetrachloride). The normal boiling
point of the solution is 61.51C, the normal
boiling point of CCl4 is 61.2C. The boiling
point constant for CCl4 is 4.95 K ยท kg/mol.
What is the molar mass of the compound?

    delta T = Kb*molality
    Solve for molality

    m = moles/kg solvent
    Solve for moles

    moles = grams/molar mass
    Solve for molar mass.
