Calculation of number of moles of KMnO4 reacting with H2C2O4
1. Given information:
- Mass of H2C2O4 = 180 g
- Balanced chemical equation: KMnO4 + H2C2O4 → 2CO2 + Mn2+
- From the balanced equation, it can be seen that 1 mole of KMnO4 reacts with 1 mole of H2C2O4.
2. Calculating the molar mass of H2C2O4:
- Molar mass of H2C2O4 = (2*1) + (2*12) + (4*16) = 90 g/mol
3. Calculating the number of moles of H2C2O4:
- Number of moles = Mass / Molar mass = 180 g / 90 g/mol = 2 moles
4. Since 1 mole of KMnO4 reacts with 1 mole of H2C2O4:
- Number of moles of KMnO4 required = 2 moles
5. Conclusion:
- Therefore, 2 moles of KMnO4 will react with 180 g of H2C2O4 according to the given reaction. This corresponds to option 'A' - 4/5.

3. Calculating the number of moles of H2C2O4:
- Number of moles = Mass / Molar mass = 180 g / 90 g/mol = 2 moles
4. Since 1 mole of KMnO4 reacts with 1 mole of H2C2O4:
- Number of moles of KMnO4 required = 2 moles
5. Conclusion:
- Therefore, 2 moles of KMnO4 will react with 180 g of H2C2O4 according to the given reaction. This corresponds to option 'A' - 4/5.
