Your work must reflect the answer provided here. An aqueous solution of sodium chloride contains 25.0% NaCl (MM=58.44 g/mol ) by mass. The density of the solution is 1.1941 g/mL at 25o Calculate number of moles[moles] of NaCl in 100g of solution, molarity[molarity], molality[molality], and mole fraction[fraction] of the solution. Assuming full dissociation of a salt, predict van 't Hoff factor[i] and calculate freezing point depression[freezing] and osmotic pressure[pressure] at 25.0oC for 2.00 molal concentration of the same salt. Kf=-1.86 °C/m. The density of the solution is 1.185 g/mL at 25o
