Urea is a common fertilizer with the formula CO(NH2)2 that is sometimes used as a chemical de-icer for icy road surfaces in the winter months. Adding a solute to a solvent causes the freezing point to be lowered and allows the solvent to remain liquid at lower temperatures. The value of Ke for water is 1.86°C/m, and its normal freezing point is 0.00°C. Urea is a nonvolatile nonelectrolyte solute. What molality of urea is required to lower the freezing point...
