Answer:
To react with 16.0 moles of sulfur we need 128.0 moles of iron (Fe).
Explanation:
Step 1: Data given
Number of moles Sulfur = 16.0 moles
Step 2: The balanced equation
8 Fe + S8 → 8 FeS
Step 3: Calculate mole Fe
For 8 moles Fe we need 1 mol S8 to produce 8 moles FeS
For 16.0 moles of Sulfur we need 8*16.0 = 128.0 moles
To react with 16.0 moles of sulfur we need 128.0 moles of iron (Fe).
The number of moles of iron needed to react with 16.0 moles of sulfur is 128.0 moles.
Given equation, 8Fe + S8 = 8 FeS
Moles of sulfur = 16.0
To react 1 mole of sulfur, we need 8 moles of Fe
So, for 16.0 moles of sulfur we need
[tex]16.0\times 8 = 128.0 moles[/tex]
Thus, to react with 16.0 moles of Sulfur, 128.0 moles of Fe is needed.
