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

Options

A. `12xx10^(23)`
B. `26xx10^(23)`
C. `34xx10^(23)`
D. `48xx10^(23)`

Answer

C

Explanation

Formula of sodium ferrocyanide, `Na_(4) [Fe(CN)_(6)]`
suggests that it has four sodium atoms.
Number of Na - atoms = Number of moles ltbr. `xx` number of atoms per number
`xx` Avogadro's number
`=2xx 4 xx 6.023xx10^(23)` Na- atoms
`= 48 xx 10^(23)` Na- atoms
