a solution is prepared by adding 1.60 g of solid nacl to 50.0 ml of 0.100 m cacl2. what is the molarity of chloride ion in the final solution? assume that the volume of the final solution is 50.0 ml.

If you are solving y2+2y=48 by completing the square, the next line would be y2 + 2y - 48 = 0 y2 + 2y + 4 = 52 y2 + 2y +1 = 49
