Answer:
[tex]1.33\text{ moles}[/tex]
Explanation:
Here, we want to get the number of moles needed to react
From the equation of reaction:
4 moles produced 6 moles of H2O
x moles will react to form 2 moles of H2O
To get the value of x, we have it that:
[tex]\begin{gathered} 4\text{ }\times\text{ 2 = 6 }\times x \\ x\text{ = }\frac{8}{6}\text{ = }\frac{4}{3}\text{ = 1.33 moles} \end{gathered}[/tex]
