7. Lactose (C12H22O11) is a sugar that is found naturally in mammalian milk. A 0.335 M solution of lactose in water has
density = 1.0432 g/mL. Determine the mole fraction of lactose (χC12H22O11), the mass percent of lactose, and the molal
concentration of this solution. mass % = _____________________
molality = _____________________
mole fraction = _____________________...
