Expert Answer
Dear Student,
 
Let x be the oxidation number of Fe.
We know that, the oxidation numbers of Na+,CN−  and NO  are +1,−1 and 0  respectively.
The sum of the oxidation numbers is zero for whole compound.
Therefore, 2(+1)+x+5(−1)+0=0  
x=+3.
Thus, the oxidation state of iron in Na2[Fe(CN)5(NO)] is +3.
