A student is given 0.733 g of an unknown acid, which can be either oxalic acid, H2C2O4, or citric acid, H3C6H5O7. To determine which acid she has, she titrates the unknown acid with 0.440 M NaOH. The equivalence point is reached when 37.0 mL are added. Answer the following questions to determine the identity of the unknown acid. How many moles of H+ acid are available to react if the acid is H2C2O4?(0.0163 mol NaOH) 1. How many moles of NaOH are consumed? Moles of NaOH = ____ mol
