The freezing point of a solution decreases with adding a solute. This is expressed in the equation below :

In the equation, **m = molality**. So we need to calculate that before we proceed.

Calculate the freezing point and boiling point of a solution containing 8.10 g of ethylene glycol (C_{2}H_{6}O_{2}) in 92.8 mL of ethanol. Ethanol has a density of 0.789 g/cm^{3}.

Calculate the freezing point of the solution.
