$5.00 \ mL$ of $0.10 \ M$ oxalic acid solution taken in a conical flask is titrated against $NaOH$ from a burette using phenolphthalein indicator. The volume of $NaOH$ required for the appearance of permanent faint pink color is tabulated below for five experiments. What is the concentration,in molarity,of the $NaOH$ solution?
$Exp. \ No.$ $Vol. \ of \ NaOH \ (mL)$ $1$ $12.5$ $2$ $10.5$ $3$ $9.0$ $4$ $9.0$ $5$ $9.0$
