Question

A solution is prepared by dissolving 17. 1 g of sucrose (C12H220,1) in 275 g of H2O.

a. What is the molar mass of sucrose?

b. What is the molality of that solution?

Answer 1

If you know the formula to use you should have no trouble getting the answers.

molality = mols/kg solvent.

mols sucrose = g/molar mass

kg solvent = 0.275 kg.
