Question

based on the following balanced equation:
3li + alcl₃ → 3licl + al
how many moles of al form from 9 moles of li?
9 mol li → ? mol al

Explanation:

Step1: Analyze mole ratio

From the balanced equation \(3Li + AlCl_3
ightarrow3LiCl + Al\), the mole ratio of \(Li\) to \(Al\) is \(3:1\).

Step2: Set up proportion

Let \(x\) be the moles of \(Al\). Using the ratio \(\frac{3\space mol\space Li}{1\space mol\space Al}=\frac{9\space mol\space Li}{x}\).

Step3: Solve for \(x\)

Cross - multiply: \(3x = 9\times1\), so \(x=\frac{9}{3}=3\).

Answer:

\(3\)
