10.00 g of glucose, C6H12O6, MWt = 180.16 g/mole, is dissolved in 200.00 g of H2O

1. Calculate the molality, m, of the glucose

2. Calculate the mole fraction, X, of the glucose.

3. 39.8 g of a sugar (nonelectrolyte) is dissolved in 200.0 g of water.
The boiling point increases by 0.30 oC.
Estimate the molecular weight of the sugar.
(Kb for water = 0.512 K kg / mole.)
