2. Saccharin is a common artificial sweetener without calories. When 3.00 g of the sodium salt of saccharin (the anion of saccharin with a Na cation) is dissolved in 50.0 mL of water, it takes 14.6 mL of 1.00 M HCl to reach the equivalence point. Using the data provided, calculate the molecular weight of sodium saccharin?
