The number of iodine atoms present in `1cm^(3)` of its 0.1 M solutions is :

A

`6.02 xx 10^(23)`

B

`6.02xx10^(22)`

C

`6.02xx10^(19)`

D

`1.204xx10^(20)`

Text Solution

Verified by Experts

The correct Answer is:
D
`1000cm^(3)` of 0.1 M solution contain
`=0.1` mole
`1cm^(3)` of 0.1 M solution contain `=(0.1)/(1000)`
`=1xx10^(-4)`mole
`1xx10^(-4)` mole of
`I_(2)=6.02xx10^(23)xx2xx1xx10^(-4)`
`=1.204xx10^(20)` atoms
