# What is the boiling point elevation of a solution composed of urea in water?

## Calculating Boiling Point Elevation

**To calculate the boiling point of a solution containing urea in water:**

- Calculate the molality of urea in the solution.
- Utilize the molal boiling point elevation constant for water.
- Determine the boiling point elevation of the solution.

## Using the Formula

**The formula for boiling point elevation:**ΔTb = Kb * m

- ΔTb: Boiling point elevation
- Kb: Molal boiling point elevation constant for the solvent
- m: Molality of the solute in the solution

## Calculation Steps

- Calculate the molality of urea in the solution as moles of urea / mass of water (in kg).
- Determine the molal boiling point elevation constant for water (0.51°C/m).
- Calculate the boiling point elevation using the formula.
- Add the boiling point elevation to the boiling point of pure water (100.0°C) to find the boiling point of the solution.

By following these calculation steps, we can accurately determine the boiling point elevation of a solution containing urea in water.
