MCQ
The unit of ebulioscopic constant is ___________.
- AK kg mol-1 or K(molality)-1
- Bmol kg K-1 or K-1(molality)
- Ckg mol-1 K-1 or K-1(molality)-1
- DK mol kg-1 or K(molality)
Explanation:
$\text{K}_{\text{b}}=\frac{\Delta\text{T}_{\text{b}}}{\text{m}}=\frac{\text{K}}{\text{mol kg}^{-1}}\text{or K}\text{(molality)}^{-1}$
The unit of ebullioscopic constant is K kg mol-1 or K molality-1
