The number of mole of oxalate ions oxidised by one mole of MnO_4^(-) i

1.	The number of mole of oxalate ions oxidised by one mole of MnO_4^(-) is
Answer» `1//5` `2//5` `5//2` `5` Solution :`overset(+7)(MnO_4^(-))overset((5))rarrMn^(2+),overset(+3)(C_2)O_4^(2-)overset((2))rarr2overset(+4)(CO_2)` `1/5` moles `MnO_(4)^(-)-=1/2` moles `C_(2)O_(4)^(2-)` 1 mol ........ ? `=5/2`
