The number of sodium atoms in 2 moles of sodium ferrocyanide is

A

`12xx10^(23)`

B

`26xx10^(23)`

C

`34xx10^(23)`

D

`48xx10^(23)`

Text Solution

Verified by Experts

The correct Answer is:
D
As we know that four sodium atom are present in sodium ferrocyanide `[Na_(4)Fe(CN)_(6)]`
Hence, number of `Na` atoms = No. of moles `xx` number of atom `xx` Avogadro's number
`2xx4xx6.023xx10^(23)=48xx10^(23)`
