Answer:
[tex]12.3\text{ moles}[/tex]Explanation:
Here, we want to get the number of moles of water that would form
From the equation of reaction, 4 moles of ammonia produced 6 moles of water
However, 8.2 moles of ammonia will produce x moles of water
To get the value of x, we have it that:
[tex]\begin{gathered} \text{ 4 }\times x\text{ = 8.2}\times\text{ 6} \\ x\text{ = }\frac{8.2\text{ }\times6}{4} \\ \text{ x= 12.3 moles} \end{gathered}[/tex]
