Solution
Correct Answer:
100.52°C
The elevation in boiling point is given by: ΔTb=Kb×m
- Molality (m): Moles of Glucose =18018=0.1 mol.
- Mass of solvent =100 g=0.1 kg.
- m=0.1 kg0.1 mol=1.0 molal.
- Elevation: ΔTb=0.52×1.0=0.52 K.
- Boiling Point: Tb=Tb0+ΔTb=100∘C+0.52=100.52∘C.
Note: The previous solution had a calculation error in the explanation text suggesting 100.052.
