A solution P was prepared by dissolving $$6.3\ \text{g}$$ of oxalic acid in $$100\ \text{mL}$$ water. $$25\ \text{mL}$$ of this solution was taken and was further diluted to $$250\ \text{mL}$$ to prepare solution Q. What weight of NaOH in ppm will be required to neutralize $$10\ \text{mL}$$ of solution Q?

A

$$10\ \text{ppm}$$

B

$$20\ \text{ppm}$$

C

$$40\ \text{ppm}$$

D
