Calculation of Van't Hoff Factor (i):
- CuCl2 ionizes into Cu2+ and 2Cl- ions
- Van't Hoff Factor (i) = 1 + 2 = 3
Calculation of Molality (m):
- Molality (m) = (moles of solute) / (kg of solvent)
- Moles of CuCl2 = 13.44g / 134.4 g/mol = 0.1 mol
- Molality (m) = 0.1 mol / 1 kg = 0.1 mol/kg
Calculation of Elevation in Boiling Point (ΔTb):
- ΔTb = i * Kb * m
- ΔTb = 3 * 0.52 * 0.1 = 0.156 K
Therefore, the elevation in the boiling point of the solution is 0.16 K.
So, the correct answer is (b) 0.16.
