Your work must reflect the answer provided here. An aqueous solution of calcium chloride contains 20.0% CaCl2 (MM=110.98 g/mol ) by mass. The density of the solution is 1.215 g/mL at 25o Calculate number of moles[moles] of CaCl2 in 100g of solution, molarity[molarity], molality[molality], and mole fraction[mole] of the solution. Assuming full dissociation of a salt, predict van 't Hoff factor[i] and calculate freezing point depression[freezing] in 0C and osmotic pressure[pressure] in atm at 25.0oC for 1.5 molal concentration of the same salt. Kf=-1.86 °C/m. The density of the solution is 1.115 g/mL at 25o
