Answer:
0.5
Explanation:
To be able to get the answer, we need to balance the ionic equation.
MnO42- + C2O42- —-> MnO2 + 2CO32-
Firstly we balance mole-wise and then charge-wise.
Let’s check If the equation is balanced.
We can see that the equation is balanced both mole-wise and charge wise
From the balanced equation we can see that 1 mole of MnO42- produced 2 moles of CO32-.
This means x moles of MnO42- will produce 1 mole of CO32-.
To get x, we simply make a cross multiplication.
2x = 1 and x = 0.5
Hence 0.5 mole of MnO42- will produce 1 mole of CO32-
