MCQ
The molal elevation constant is the ratio of the elevation in B.P. to
- AMolarity
- ✓Molality
- CMole fraction of solute
- DMole fraction of solvent
✓
Answer
Correct option: B.
Molality
b
(b)$\Delta {T_b} = {K_b} \times m$ or ${K_b} = \Delta {T_b}/m$
(b)$\Delta {T_b} = {K_b} \times m$ or ${K_b} = \Delta {T_b}/m$
