Estimate the freezing point of 150 cm3 of water sweetened with 7.5g of sucrose
(C12H11O22). (Kf for water is 1.86 K kg mol-1; density of water is 1gcm-3)
Answered by DrBob222
moles sucrose = grams/molar mass. Solve for moles.
molality = moles sucrose/kg solvent. Solve for molality.

delta T = Kf*molality.
solve for delta T and from there the freezing point.
