Why is it necessary to express the concentration of solute in units of molality rather than molarity? The molality is based on the volume of the entire solution, whereas molarity is based only on the volume of the solvent. Molality will be constant at any temperature, whereas the concentration can change as the solution expands with heat. O The molality is based on the mass of the entire solution, whereas molarity is based only on the mass of the solvent.

Calculate the molality of a copper (ll) nitrate solution which contains 35.0 g of copper (ll) nitrate in 165 g of water.
We mixed some ethylene glycol with 346 g water to reduce the equilibrium vapor pressure of water from 23.76 Hg to 22.5 Hg at 25°C. The molar masses of water and ethylene glycol are 18.02 g/mol and 62.07 g/mol, respectively. Assume ideal behavior for the solution. What is the boiling point of this solution? (Hint: find the molality first, and for water, kb = .510 m/°C; boiling point of water: 100.0°C.)
