Atom composition (simple question but hard for me)

Click For Summary
SUMMARY

The discussion focuses on determining the value of x in the compound Fe3(Co)x, where iron (Fe) constitutes 33.26% by mass. The initial calculation attempted to derive x as 5.6, but the correct answer is established as x=12. The confusion regarding the notation of cobalt (Co) versus carbon monoxide (CO) is clarified, confirming that Co refers to cobalt in this context.

Homework Statement



Fe3(Co)x, Fe is 33.26% by mass. Find the value of x.

The Attempt at a Solution



167.5425 g / 0.3326 = x ( 58.9326 g) / 0.6628

x = 5.6...

but the right answer given was x=12.
