Calculate the number of grams of Fe formed when 0.300kg of Fe2O3 reacts.
Equation:
Fe2O3+CO-->Fe+CO2

converted .300kg to 300g
Balanced Fe2O3+3CO-->2Fe+3CO2

So I started by trying this:
300gFe2O3(1molFe2O3/159.687gFe2O3)...and then I don't know where I would go from there. I'm not even sure if I'm even starting off right. I'm trying to follow along with the teacher's notes, but she didn't have anthing like this.

• Chem -

how many moles of Fe2O3 do you have? figure that.
Then, the balanced equation tells you that you get twice that number of moles of Fe.

300gFe2O3(1molFe2O3/159.687gFe2O3)*2moleFe/1moleFe2O3

Yeah, I balanced it already; I put it up. My teacher didn't do this, that's why I didn't know how to start, but is that pretty much all I have to do? That extra multiplication/division?

• Chem -

Just to clarify, when I convert from moles to grams, do I double Fe because it has the coefficient 2?

• Chem -

I got the answer (210grams). Thanks.

Can you balance this equation please? Fe2O3 + CO yeilds Fe + CO2 Fe2O3 + CO ==> Fe + CO2 Rule: balance by changing coefficients. You may not change subscripts. Look at the Fe atoms. There are 2 Fe atoms on the left and only 1 on
