1. Calculate the molarity of a solution containing 49.3g of dissolved naphthalene (C10H8) in 217g benzene (C6H6). 2. A solution is prepared by mixing 94.2g of H2O, and 58.7g of ethanol, C2H5OH. Determine the mole fractions of each substance.

3. If you use 2.17mol of sucrose (C12H22O12) and dissolve this into 0.500kg of H2O, what will be the change in the freezing point of your solution? The freezing point depression of water (Kf) is 1.86 degrees Celsius/m.
