Answer:
The answer to your question is 3 moles of Fe and 4.5 moles of S
Explanation:
Data
moles of Fe = ?
moles of S = ?
moles of Fe₂S₃
Unbalanced chemical reaction
Fe + S ⇒ Fe₂S₃
Reactants Elements Products
1 Fe 2
1 S 3
Balanced chemical reaction
2Fe + 3S ⇒ Fe₂S₃
Reactants Elements Products
2 Fe 2
3 S 3
-Calculate the moles of each reactant
2 moles of Fe ------------------- 1 mol of Fe₂S₃
x -------------------- 1.5 moles Fe₂S₃
x = (1.5 x 2) / 1
x = 3 moles of Fe
-Calculate the moles of S
3 moles of S --------------------- 1 mol of Fe₂S₃
x --------------------- 1.5 moles of Fe₂S₃
x = (1.5 x 3) / 1
x = 4.5 moles of S
