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

A

`12 xx10^(23)`

B

`26 xx 10^(23)`

C

`34 xx10^(23)`

D

`48 xx 10^(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 `2 xx 4 xx 6.023 xx 10^(23) = 48 xx 10^(23)`
