A solution was made by dissolving 10.0g of a nonvolatile nonelectrolyte compound in 100.0g of water froze at -0.93C. What is the approximate molecular weight of the substance. (for water..kf=1.86C/m) (m is molality)

  • chemistry -

    delta T = Kf*m
    Solve for m

    m = moles/kg solvent
    Solve for moles.

    moles = grams/molar mass
    Solve for molar mass.
