based on the following balanced equation: 3rb + p → rb₃p how many moles of rb₃p form from 12 moles of rb? 12 moles rb → ? moles rb₃p
Answer
Explanation:
Step1: Identify mole - ratio
From the balanced equation $3Rb + P\rightarrow Rb_3P$, the mole - ratio of $Rb$ to $Rb_3P$ is $3:1$.
Step2: Set up conversion
Let $x$ be the number of moles of $Rb_3P$. We use the mole - ratio to set up the proportion $\frac{3\ moles\ Rb}{1\ mole\ Rb_3P}=\frac{12\ moles\ Rb}{x}$.
Step3: Solve for $x$
Cross - multiply: $3x = 12\times1$. Then $x=\frac{12\times1}{3}$. $x = 4$.
