**Task:**

Calculate the $\mathrm{H}_2\mathrm{C}_2\mathrm{O}_4$ (aq) molarity if 10.00 ml of its solution reacts completely with 31.5 ml of a 0.0158 M KMnO₄?

**Answer:**

$$C _ {M} \left(H _ {2} C _ {2} O _ {4}\right) \cdot V \left(H _ {2} C _ {2} O _ {4}\right) = C _ {M} \left(K M n O _ {4}\right) \cdot V \left(K M n O _ {4}\right)$$ $$C _ {M} \left(H _ {2} C _ {2} O _ {4}\right) = \frac {0 , 0 1 5 8 \cdot 3 1 , 5}{1 0 , 0 0} = 0, 0 5 M$$
