200 g of a non-electrolye is dissolved in 1000 g of water. The boiling point of the solution is then measured to be 101.5 C. What is the molar mass?
(the Kb for water is 0.51 C/m)

I know deltaT = 0.51 C/m but where do I go from there?

  • Chemistry -

    delta T = Kb*m
    Calculate m

    m = moles/kg solvent.
    Calculate moles

    moles = grams/molar mass
    Calculate molar mass.
