Question

how many moles of fe are required to form 12 moles of fes? 2fe + 2s → 2fes

Explanation:

Step1: Analyze the stoichiometric ratio

From the balanced chemical equation \(2Fe + 2S
ightarrow2FeS\), the ratio of \(Fe\) to \(FeS\) is \(2:2 = 1:1\).

Step2: Calculate the moles of \(Fe\)

If \(n(FeS)=12\space mol\), using the ratio \(\frac{n(Fe)}{n(FeS)} = 1\), then \(n(Fe)=n(FeS)\times1\).

Answer:

\(12\space mol\)
