Vitamin C, Molar mass 176.12 g/mol, is a compound of C, H, and O, and found in many natural sources, especially citrus fruits. When 1.000 g sample of vitamin C is burned in a combustion apparatus, the following data are obtained:Mass of CO2 absorber after combustion = 85.35 gMass of CO2 absorber before combustion = 83.85 gMass of H2O absorber after combustion = 37.96 gMass of H2O absorber before combustion = 37.55 gWhat is the molecular formula for vitamin C? [C = 12.01, H = 1.01, O = 16.00]
