2) The stimulant in coffee and tea is caffeine, a substance of molar mass 194 g/mol. When 0.376 g of caffeine was burned, 0.682 g of carbon dioxide, 0.174 g of water, and 0.110 g of nitrogen gas were formed. If caffeine is made of carbon, hydrogen, nitrogen, and oxygen, determine the empirical and molecular formulas of caffeine, and write the balanced equation for the combustion of caffeine. Balanced Combustion Equation
