`1.5`

B

2

C

3

D

1

Text Solution

Verified by Experts

The correct Answer is:
B
`FeC_(2)O_(4)+KMnO_(4)rarrFe^(3+)+CO_(2)+Mn^(2+)`
v.f. = 3 v.f = 5
`1xx3` = mole `xx5`
Mole = `(3)/(5)`
`Fe_(2)(C_(2)O_(4))_(3)+KMnO_(4)rarrFe^(3+)+CO_(2)+Mn^(2+)`
v.f. = 6 v.f = 5
`1xx6` = mole `xx5`
Mole = `(6)/(5)`
`FeSO_(4)+KMnO_(4)rarrFe^(3+)+SO_(4)^(2-)+Mn^(2+)`
v.f = 1 v.f = 5
`1xx1` = moles `xx5`
Mole = `(1)/(5)`
`Fe_(2)(SO_(4))_(3)` doesn.t oxidize
Total moles of `KMnO_(4)=(3)/(5)+(6)/(5)+(1)/(5)=2`.
