A 0.5537-g sample containing oxalic acid required 21.62 mL of 0.09377 M NaOH for titration. If the reaction is H2C2O4 + 2NaOH Na2C2O4 + 2H2O, calculate the % H2C2O4 in the sample.

Here is a worked example of a stoichiometry problem. Just follow the steps to obtain the theoretical yield.
Then %H2C2O4 = (mass H2C2O4/mass sample)*100 = (mass H2C2O4/0.5537)*100 = ?
Post your work if you get stuck. And keep the same screen name whether it be Polly, Meg, Tanya, or you name it.
