Problem 2 (16 points): In a winter country, a winemaker is waiting for her grapes to freeze in order to make a special batch of holiday ice wine. Recent analysis has shown that the grapes are currently 30% glucose by mass. Assume that glucose (formula C6H12O6 MW= 180 g/mol) is the only solute present and that water is the solvent. Use Kfwater = 1,86°C kg/mol.
