Question 3 A student analyzed impure samples of oxalic acid dihydrate (MM = 126.08 g/mol) using a (1.193x10^-1) M solution of NaOH. If a (4.63x10^-1) gram sample of impure acid required (3.6610x10^1) mL of NaOH to reach the end point of the titration, how many moles of oxalic acid dihydrate were in the original sample? Enter your answer in scientific notation with three significant figures. Do not include any units in your answer. Note: Your answer is assumed to be reduced to the highest power possible.
