While doing a titration, a student recorded a burette reading of 10.0 mL for the neutralization of 10.0 mL $$\text{NaHC}_2\text{O}_4$$ (aq) with 0.1 M NaOH (aq). In a separate experiment, 10.0 mL of this $$\text{NaHC}_2\text{O}_4$$ (aq) solution could be completely oxidized by 10.0 mL of $$\text{KMnO}_4$$ in an acidic medium. What would be the molarity of $$\text{KMnO}_4$$ used by this student?

A

0.02 M

B

0.04 M

C

0.1 M

D

0.2 M
