The molarity (m) of `KMnO_(4)` in the acidic medium is (densityh of `KMnO_(4)` solution`=1.58gmL^(-1)Mw(KMnO_(4))=158gmol^(-1))`

A

0.025

B

0.25

C

0.12

D

0.012

Text Solution

Verified by Experts

The correct Answer is:
D
`d_(sol)=M((Mw_(2))/(1000)+(1)/(m))`
`M=0.02`
`1.58=0.02((158)/(1000)+(1)/(m))`
Solve for m:
`m=0.012`
