Question

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

Explanation:

Step1: Analyze the mole ratio

From the balanced equation \(3Rb + P
ightarrow Rb_3P\), the mole ratio of \(Rb\) to \(Rb_3P\) is \(3:1\).

Step2: Set up the proportion

Let \(x\) be the moles of \(Rb_3P\). Using the ratio \(\frac{3\space mol\space Rb}{1\space mol\space Rb_3P}=\frac{12\space mol\space Rb}{x}\).
Cross - multiply: \(3x = 12\times1\).

Step3: Solve for \(x\)

Divide both sides by 3: \(x=\frac{12}{3}=4\).

Answer:

\(4\)
