If 1373 g of a substance is dissolved in 2315 g of cyclohexane solvent, the boiling point of the solution is 87.69 oC. Calculate the apparent molar mass (g/mol) of substance.

  • chemistry -

    delta T = Kb*molality
    Calculate molality, then
    molality = moles/kg solvent
    Calculate moles, then
    moles = g/molar mass,
    calculate molar mass.
    Post your work if you get stuck.

    You will need to look up the boiling point of cyclohexane if it isn't given in the problem.
