A

twice that of its molecular weight

B

equal to its molecular weight

C

one-half of its molecular weight

D

one-third of its molecular weight

Text Solution

Verified by Experts

The correct Answer is:
B
`2KMnO_(4)+3H_(2)SO_(4)rarrK_(2)SO_(4)+2MnSO_(4)+3H_(2)O+5(O)`
`10overset(+2)(F)eSO_(4)+5H_(2)SO_(4)+5(O)rarr5overset(+3)(F)e_(2)(SO_(4))_(3)+5H_(2)O`
Eq. wt of `FeSO_(4)=("mol wt of "FeSO_(4))/(1)`
