1. Calculate the mass percent of water in 2.00M CaCl₂(aq). The density of the solution is 1.032g/mL.

2. The dissolution of water in benzene (C₆H₆) is prevented by:

		relatively strong hydrogen bonding forces between water molecules.
		relatively strong interactions formed between water and benzene.
		relatively strong dipole-dipole attractions between benzene molecules.
		relatively weak London dispersion forces between benzene molecules.
