Calculate the amount of CaCl2 (molar mass =111gmol−1) which must be – InterviewSolution

1.	Calculate the amount of CaCl2 (molar mass =111gmol−1) which must be added to 500 g of water to lower its freezing point by 2K, assuming CaCl2 is completely dissociated. (Kf for water =1.86Kkg mol−1).
Answer» Calculate the amount of $C a C l_{2}$ (molar mass $= 111 g m o l^{- 1})$ which must be added to 500 g of water to lower its freezing point by 2K, assuming $C a C l_{2}$ is completely dissociated. $(K_{f}$ for water $= 1.86 K k g m o l^{- 1})$ .
