A sample of an Iron Oxalato complex salt weighting 0.13 grams requires 32.74 mL of 0.01 M KMnO4 to turn the solution a very light pink color at the quivalence point. Calculate the number of moles of KMnO4 added.

The number of moles of added are 0.0003

Explanation:

To calculate the number of moles for given molarity, we use the equation:

    .....(1)

Molarity of solution = 0.01 M

Volume of solution = 32.74 mL

Putting values in equation 1, we get:

Thus the number of moles of added are 0.0003
