Determine the melting point of an aqueous solution containing 115 mg of saccharin (C7H5O3NS)added to 1.00 mL of water (density of water=1.00 g/mL, Kt=1.86 C/m)

mols saccharin = 0.115g/molar mass
Solve for mols.

m = mols/kg solvent
m = mols/0.001
solve for m

delta T = Kf*m
Solve for delta T and subtract from 0 C to find the melting point.
