A sаmple thаt cоntаins 53.66% оf оxalic acid by, H2C2O4, by mass is reacted with sodium hydroxide (NaOH) for neutralization. If a 0.6543 g of the oxalic acid sample is reacted, what is the volume (in mL) of 0.3483 M NaOH required for the neutralization. Hint: Do not forget the percent composition of oxalic acid. Must show your work on scratch paper to receive credit. 2 NaOH(aq) + H2C2O4(aq) → Na2C2O4(aq) + 2 H2O(l)
