Question

The unit of ebullioscopic constant is

• A. K or K $ {{(molality)}^{-1}} $
• B. $ mol\,kg\,{{K}^{-1}} $ or $ {{K}^{-1}}(molality) $
• C. $ kg\,mo{{l}^{-1}}{{K}^{-1}} $ or $ {{K}^{-1}}{{(molality)}^{-1}} $
• D. $ Kmol\,k{{g}^{-1}} $ or $ K(molality) $

Answer 1

Answer: (A)

The unit of ebullioscopic constant, $ {{\text{K}}_{\text{b}}}=\text{Kkgmo}{{\text{l}}^{-1}} $ or $ \text{K}\,{{\text{(molality)}}^{-1}}. $
