Calculate the molarity of a sodium hydroxide solution?

use a t chart. start with mL of oxalic acid over mL of NaOH. then, conver the mL of oxalic acid into moles of NaOH using the molarity of the oxalic acid and mole to mole ratios using the balanced chemical equation. finally, turn the mL of NaOH, which is conveniently in the denominator of the t-chart, into liters. when you do all the multiplication/division required by the t chart, your answer should be the molarity of the NaOH
