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. What is the mass of glucose present?  How many moles of glucose are there (three significant figures)? What is the mass of water present (in grams)? (Hint: Solution - Solute = Solvent) What is the molality of sucrose in water? What is the freezing point of the grapes (deg C)? What is the freezing point (deg C) if the molality of the glucose in water is 2.16 mol/kg?
