Academics

Question- Could CaCl2 melt ice at -36 degrees Celsius? Assume that the solubility of CaCl2 at this temp is 70.1 g CaCl2/100 g of H2O and that the van't Hoff factor for a saturated solution of CaCl2 is i=2.5.

What is the minimum amount of CaCl2 that would be required to melt ice on sidewalks at the above temperature? Use 100 g of water as the amount of solvent.

I need help for above question. Show each steps for the above problem.
