Glyoxyl, used in textiles; maleic acid, used to retard oxidation of fats and oils; and acontic acid, a plasticizer, all have the same empirical formula, CHO. However, glyoxyl has a molar mass of about 58 g/mol, maleic acid about 116 g/mol, and acontic acid about 174 g/mol.
What are the molecular formulas of glyoxyl, maleic acid, and acontic acid?
