My chemistry group are stuck on this problem and honestly do not know where to begin so if you could help out that would be great!
Saccharin is an artificial sweetener that is also a weak acid. It has the formula C7H5NSO3, and its pKa is 11.68. A 12-oz (350-mL) can of diet cola contains 3.0 mg saccharin and has a pH of 4.50. What are the equilibrium molar concentrations of saccharin and the saccharide ion?
