Question

based on the following balanced equation: 2h₂ + o₂ → 2h₂o how many moles of h₂o form from 4 moles of o₂? 4 moles o₂ → ? moles h₂o

Explanation:

Step1: Determine the mole ratio

From the balanced equation \(2H_2 + O_2 \to 2H_2O\), the mole ratio of \(O_2\) to \(H_2O\) is \(1:2\).

Step2: Calculate moles of \(H_2O\)

If there are \(4\) moles of \(O_2\), using the mole ratio \(\frac{2\space mol\space H_2O}{1\space mol\space O_2}\), the number of moles of \(H_2O\) is \(4\space mol\space O_2\times\frac{2\space mol\space H_2O}{1\space mol\space O_2}=8\space mol\space H_2O\)

Answer:

\(8\)
