When 24.0g og glucose(a nonelectrolyte) are dissolved in 500g of water, the solution has a freezing point of -0.47C. What is the molar mass of glucose according to yhe data?Kf of water is 1.86C/m.

1 answer

delta T = Kf*molality
Substitute and solve for molality.

m = moles/kg solvent
Substitute and solve for moles.

moles = grams/molar mass
Substitute and solve for molar mass.
