1. Water at 25.0C exposed to air at 1.50 atm pressure can contain a maximum of 13.7 mg/L of nitrogen gas. Calculate the value of Henry’s law constant (mol/L atm) for nitrogen at this temperature. The mole fraction of nitrogen in air is 0.78084.
2. If 125 mL of aqueous solution with a density of 0.810 g/mL contains 10.7 mL of CH3CH2OH (ethanol). Pure ethanol has a density of 0.789 g/mL. (water is the solvent and ethanol is the solute) What is the freezing point of the solution? (Kf (water) 1.86C/m)
