Answer the following questions. Show the answers here. After uploading your exam, take the pictures of your work and upload them to Exam 1 Solutions, Extra Credit, and Partial Credit assignment. 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 of CaCl2 in 100g of solution, molarity, molality, and mole fraction of the solution. Assuming full dissociation of a salt, predict van ‘t Hoff factor and calculate freezing point depression in 0C and osmotic 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
