A 0.0230 g sample of an unknown was dissolved in 2.260 g of benzene. The molality of this solution, determined by freezing point depression, was 0.0408 m. What is the molecular weight of the unknow substance?

  • chemistry - ,

    delta T = Kf*m
    Solve for m

    m = mols/kg solvent
    Solve for mols

    mols = grams/molar mass
    Solve for molar mass.
