Question 7 0.1 / 1 point You titrated a 22.00 mL solution of 0.0300 M oxalic acid with a freshly prepared solution of KMnO4.


You titrated a 22.00 mL solution of 0.0300 M oxalic acid with freshly prepared solution of KMnO4. If it took 48.99 mL of this solution, what is the molarity of the KMnO4?

0.022 L of 0.300 M oxalic acid
(0.022)(0.03) = 0.00066 mol oxalic acid
0.0006 mol oxalic acid x (2 mol KMnO4)/(5 mol oxalic acid)= 0.000264 mol KMnO4

0.000264 mol/0.04899 L = 0.05388855 M KMnO4

= 0.005388 M KMnO4

where did I go wrong?
