1. A solution was prepared by dissolving 18.00g of glucose in 150.0g of water. The resulting solution was found to have a boiling point of 0.34°C higher than its pure solvent boiling point at 1 atm. Calculate the molar mass of glucose. Glucose is a molecular solid that is present in individual molecules in solution.
