Hello dear classmate,

Your method of solving the problem would exactly what I would do. The beautiful thing about chemistry is that there are multiple ways about solving a problem. However, there is a mistake in one of your steps which is why your answer is off from the solutions manual. When you multiplied the molarity by 2 in order to get the molarity of Na+ in the solution, your decimal is off. .797 x 2 is 1.594, not .1594 :) I am not sure if that was just a typo or not, but very good job setting and doing the problem.

Best Regards,
