How many milliliters of 0.242 M NaOH are required to exactly titrate 18.0 grams of H2C2O4?

Answer 1

H2C2O4 + 2NaOH ==> Na2C2O4 + 2H2O
mols H2C2O4 = grams/molar mass
Using the coefficients in the balanced equation, convert mols H2C2O4 to mols NaOH.
Then mols NaOH = M x L. You know mols and M, solve for L and convert to mL.
