An organic compound contains carbon, hydrogen, and sulfur. A sample of it with a mass of...

An organic compound contains carbon, hydrogen, and sulfur. A sample of it with a mass of 2.712 g was burned in oxygen to give gaseous CO2, H2O, and SO2. These gases were passed through 311.2 mL of an acidified 0.0200 M KMnO4 solution, which caused the SO2 to be oxidized to SO42-. Only part of the available KMnO4 was reduced to Mn2+. Next, 31.12 mL of 0.0300 M SnCl2 was added to 31.12 mL portion of this solution, which still...
