Can u show picture because without picture I don’t understand the problem u trying to explain
Answer:
57.3mL of 0.250M KMnO4 are required
Explanation:
3.225g of oxalic acid are:
3.225g×(1mol / 90.03g) = <em>0.03582mol of oxalic acid</em>
Based on the reaction, 5 moles of oxalic acid react with 2 moles of KMnO4, thus, for a complete reaction of oxalic acid you need:
0.03582mol of oxalic acid × (2mol KMnO4 / 5mol Oxalic Acid) = <em>0.01433mol of KMnO4</em>
<em />
If concentration of KMnO4 is 0.250M, liters in 0.01433mol are:
0.01433mol × (1L /0.250mol) = 0.0573L ≡<em> 57.3mL of 0.250M KMnO4 are required</em>
