At 25°C and 1 atm, 70.80 g of sucrose (C12H22O11, sugar, MM = 342.30 g/mol) is dissolved in 100.0 g water (H20, MM = 18.02 g/mol). The solute, sucrose, is a nonelectrolyte. Meanwhile water, the solvent, has Kf and Kb values of 1.86 °C/m and 0.512 °C/m, respectively. The vapor pressure of pure water at 1 atm and 25°C is 23.8 mmHg.
