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

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