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
Answer
Explanation:
Step1: Identify mole - ratio
From the balanced equation $3Li + AlCl_3\rightarrow3LiCl + Al$, the mole - ratio of $Li$ to $Al$ is $3:1$.
Step2: Set up proportion
Let $x$ be the number of moles of $Al$. We have the proportion $\frac{3\ mol\ Li}{1\ mol\ Al}=\frac{9\ mol\ Li}{x}$.
Step3: Solve for $x$
Cross - multiply: $3x = 9\times1$. Then $x=\frac{9\times1}{3}=3$.
