Number of `K^(+)` ions present in one litre of `M//5KMnO_(4)` solution are:

A

`10xx10^(24)`

B

`1.024xx10^(23)`

C

`6.02xx10^(23)`

D

`3.01xx10^(24)`

Text Solution

Verified by Experts

The correct Answer is:
B
Milli-mole of `KMnO_(4)=1000xx(1)/(5)=200`
`:. 1 "mole of" KMnO_(4)` has `N_(A)K^(+)` ions
`:. 0.2 "mole of"KMnO_(4)` has `0.2xxN_(A)K^(+)"ions"`
