0.9 g urea when dissolved in 45 g water caused elevation of `0.17^(@)C` in b.p. Calculate molecular elevation constant of water.

Text Solution

AI Generated Solution

To calculate the molecular elevation constant (Kb) of water based on the given data, we can follow these steps: ### Step 1: Understand the relationship between boiling point elevation and molality The elevation in boiling point (ΔTb) is directly proportional to the molality (m) of the solution. The relationship is given by the formula: \[ \Delta T_b = K_b \cdot m \] where: ...
