Saccharin is the active ingredient in many sweeteners used today. It is made up of carbon, hydrogen, oxygen, sulfur, and nitrogen. When 7.500 g of saccharin are burned in oxygen, 12.6 g CO2, 1.84 g H2O, and 2.62 g SO2 are obtained. Another experiment using the same mass of sample (7.500 g) shows that saccharin has 7.65% N. What is the simplest formula for saccharin?
C7H16(g) + O2(g) → C2H2(g) + O2(g) → C3H8O(g) + O2(g) → HCl(aq) + NaOH(aq) → CH3OH + O2(g) → NaI(aq) + Cl2(g) → Li(s) + N2(g) → C3H6(g) + O2(g) → AlCl3(s) → Ca(s) + HCl(aq) → LiOH(aq) + Fe(NO3)3(aq) →
