Calculating Iron (II) Sulfide: Stoichiometry Help & Equation Explanation

[nduncan2010]

stoichiometry--hellp please!

1. How much Iron should be combined with sulfur to produce 56.8 grams of iron (II) Sulfide



2.



3. ok.. so this is what i have ..
Fe + S ----> FeS ----correct??

Then. molar ratios are 1-1-1..
The molar ration between Fe and FeS is 1:1
Fe-55.8
S-32.1
--------
= 87.9

56.8 /87.9 *1*55.8 = 36.1 g FeS.. is this correct? the wording in the equation is different then all of the other equations on my worksheet soo I am not sure if this is right.

Your type-setting or your text formatting is not good. You want to show as:
(56.8 /87.9) *1*55.8 = 36.1 g Fe
That then would be good.

NOTE: why the forum does not allow text strike-out? I meant to show previous post's answer for FeS which was wrong, and then make a 'scratch' mark through the S; because the 36.1 grams is for the IRON.
