Table 1: Standardization of KMnO4

Trial 1

Trial 2

Vol Na2C2O4 (mL)

10 mL

Initial Buret (mL)

0 mL

13.8 mL

Final Buret (mL)

25 mL

Vol KMnO4 (mL)

11.2 mL

Moles C2O42-(mol)

0.0005 mol

Moles KMnO4(mol)

0.0002 mol

Molarity KMnO4(M)

Average Molarity (M)

Given the above data how do I calculare the molarity of KMnO4(M) and the average moalrity (PLEASE INCLUDE CALCULATIONS! that way i can understand how the values were found thanks :)
