Question

Calculate boiling point and freezing point of this solution which contains 5.85g of C6H12O6 in 255g H2O. pleasee

Answer 1

mols C6H12O6 = grams/molar mass = ?

Then m = molality = mols/kg solvent. You know kg solvent and mols, solve for m.

Then delta T = Kf*m and solve for dT, then subtract from 0 to find new freezing point.
OR, delta T = Kb*m and solve for dT then add to 100 to find the new boiling point.
