When 25.00 mL of unknown were passed through a Jones reductor, molybdate ion (MoO 2- 4 )

Question:

When 25.00 mL of unknown were passed through a Jones reductor, molybdate ion (MoO^2-₄) was converted into Mo³⁺. The filtrate required 16.43 mL of 0.010 33 M KMnO₄ to reach the purple end point.

MnO^-₄ + Mo³⁺ → Mn²⁺ + MoO₂²⁺

A blank required 0.04 mL. Balance the reaction and find the molarity of molybdate in the unknown.
