Total molar mass of K4[Fe(CN)6] = 368 g/mol
Mass of 1 mol of K4[Fe(CN)6] = 368 g/mol
So, Mass of 5 mol of K4[Fe(CN)6] = 368 x 5 g/mol = 1840 g/mol
Mass of C in K4[Fe(CN)6]= 6 x 12=72 g/mol
Let mass of Carbon in this compound is A
Then, A/1840 = 72/368 = 36 g/mol
Mass of carbon in 5 mol is 360 g/mol
