Question

what mass of nacl(s) (mw 58.44) would have to be added to 800 ml of water so that the resulting solution has the same freezing point as the cucl2(aq) solution described above? assume ideal solutions. enter the mass of nacl(s) in g. (round to 1 decimal place.) (do not enter units.)

Answer 1

11.7 g

Step-by-step explanation:

The freezing point of a solution is lowered by the addition of solute particles. In order to have the same effect on freezing point as the CuCl2 solution, 11.7g of NaCL must be added.
