Asked by Drew

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)
Answered by DrBob222
delta T = Kf*m
Solve for m

m = moles/kg solvent
Solve for moles.

moles = grams/molar mass
Solve for molar mass.
