Suatu larutan urea dalam air mempunyai penurunan titik beku 5,58°c. Bila kf molal air = 1,86 °c dan kb molal air = 0,52 °c, maka kenaikan titik didih larutan urea tersebut adalah
Accepted Answer
The question involves calculating the boiling point elevation of a urea solution. Here's the solution:
1. Calculate the molality of the urea solution:
- ΔTf = Kf
molality
- 5.58 °C = 1.86 °C/molal
molality
- molality = 3 molal
2. Calculate the boiling point elevation (ΔTb):
- ΔTb = Kb
molality
- ΔTb = 0.52 °C/molal
3 molal
- ΔTb = 1.56 °C
Therefore, the boiling point elevation of the urea solution is 1.56 °C.
