Title: How can I figure out how much pure iron I have?
Post by: tobyn224 on May 07, 2022, 10:11:29 PM

If someone can tell me how to do this question as a whole, that'd be great. I'm just not even sure where to start to be honest so if someone can walk be through it that'd be great.

Problem: I have 50lbs of iron (III) oxide. I am heating it up to remove the oxygen and produce pure iron. I want to know how many pounds of iron I can get from my sample so I can forge knives. Each knife weighs roughly 2.65oz. How many knives can I forge from 50lbs of iron rust (aka iron (III) oxide)?

There is a suggestion that often applies to this kind of situation.
