Question 20 of 20 Submit You have an aqueous solution of NaCl that has a freezing point of -4.25°C. What mass (in grams) of NaCl must be added to 1000 g of this solution to lower the freezing point to -12.00°C? (Assume a van't Hoff factor of 1.9 for NaCl). (Kf for water is 1.86°C-kg/mol). g 2 C 7 8 +/- x 100 Show l 3. 1. 4.
