Expert Answer:

Potassium ferrocyanide is  K4[Fe(CN)6]
Moles of  potassium ferro cynide=weight of ferro cynide/molecular weight of potassium ferro cynide
=2.5 moles of potassium ferro cynide
and, we can see one potassium ferro cynide have 6 carbon.
so, number of moles of carbon=6*2.5=15 moles 
15=weight of carbon/Molecular weight of carbon
wt of carbon=180 g.
