Explain ice to cool a concentrated nacl solution

Reference no: EM13214314

Home ice cream makers use ice to cool a concentrated NaCl solution below the normal freezing point of water. What molal concentration of salt is needed to lower the freezing point to -4.49 C? Assume that the solution is ideal, and that the van't Hoff factor for NaCl is the expected (ideal) value.
