Stoichiometry and Chemical Analysis

Mar 2020
G'day all,

Since this question is bugging me and I am starting to suspect that I have not been given the required information, I'm looking for some help. The question is as follows:


I am able to figure the moles of Fe via this equation: 762g Fe * (1mol Fe/55.85g Fe) = 13.6436884512mol Fe.

From here, I don't understand how to progress as I have not been given an equation that I would use to determine a ratio between moles of Fe and Fe(3)O(4).

Is there a way to determine how many moles of Fe are in a mole of Fe(3)O(4)?

Looking forward to your reply,
