Succinic acid only contains C, H, and O elements. It has two acidic hydrogens that react with NaOH. 2.24 g CO2 and 0.685 g H2O are obtained after the complete combustion of 1.50 g of succinic acid. The complete reaction of 1.50 g of succinic acid with 0.892 M NaOH needed 28.5 mL of the base. Determine the empirical and molecular formulas of succinic acid.
