Question 15 5 pts A student is told that a solution of 1.15 g of an unknown ionic compound dissolved in 10.0 g of water freezes at -2.23 °C. She is told to assume the solution has ideal behavior. She is also told the unknown is one of the compounds given below. Which of the ionic compounds is her unknown? The freezing point of water is 0 °C and Kf = 1.86 °C/m. = barium sulfate, BaSO4 (MM = 233.4 g/mol) strontium perchlorate, Sr(ClO4)2 (MM = 286.6 g/mol) = cesium iodide, Csl (MM = 259.8 g/mol) aluminum nitrate, Al(NO3)3 (MM = 213 g/mol) =
