A) \[12\times {{10}^{23}}\]
B) \[26\times {{10}^{23}}\]
C) \[34\times {{10}^{23}}\]
D) \[48\times {{10}^{23}}\]
Correct Answer: D
Solution :
Formula of sodium ferrocyanide i.e., \[N{{a}_{4}}[Fe{{(CN)}_{6}}]\] suggests that it has four sodium atoms. Number of Na atoms = number of moles \[\times \] number of atoms per molecule \[\times \] Avogadro number \[=2\times 4\times 6.023\times {{10}^{23}}\] \[=48\times {{10}^{23}}\]You need to login to perform this action.
