To make a solution, 40 g of a nonelectrolyte is dissolved into 300 g of water. The freezing point depression of the solution is measured to be -7°C. Calculate the molar mass of the solute.

Formaldehyde has a distribution coefficient, KD = 0.111 at 25°C. How many liters of water will be required to remove in one extraction, 95% of the formaldehyde from 1.0 L of ether containing 0.5 g, of formaldehyde?

Magnesium can be determined gravimetrically by precipitating as NH4MgPO4. A 1.291 g sample was dissolved and the magnesium precipitated as NH4MgPO4. The precipitated was collected, rinsed and ignated to constant weight as Mg2P2O7, yielding 0.1258 g. Calculate the %w/w Mg in the sample.
