solutions in acetic acid. The Kf for acetic acid is 20.0C/m and the Tf=16.6C. a. Calculate the freezing point of a solution that contains 10.0g of KCl (molar mass =74.55 g/mol ) in 0.50L of acetic acid (density =1.05kg/L ). b. Calculate the freezing point of a solution that contains 10.0g of CaCl2(110.98g/mol) in 0.50L of acetic acid (density =1.05kg/L ). c. For an ionic compound that has a+2 charged cation and a chloride anion, the freezing point of 10.0g solution in 0.50L of acetic acid (density =1.05kg/L ) was found to be 4.5 C. What is the identity of the cation? Hint: determine the molar mass first! 8. 8 points: Calculate the molality of a 0.79MNaHCO solution if its density =1.19g/mL
