Answer:
44.4 moles of NH3.
Explanation:
You can see that in the chemical equation, we have that 4 moles of NH3 reacted produces 6 moles of H2O. We can state the rule of three to find how many moles of NH3 we need to produce 66.6 moles of H2O, like this:
[tex]\begin{gathered} \text{4 moles NH}_3\rightarrow6\text{ moles H}_2O \\ ?\text{ moles NH}_3\rightarrow66.6\text{ moles H}_2O. \end{gathered}[/tex]
The calculation would be:
[tex]66.6\text{ moles H}_2O\cdot\frac{4\text{ moles NH}_3}{6\text{ moles H}_2O}=44.4\text{ moles NH}_3.[/tex]
We will need 44.4 moles of NH3 to produce 66.6 moles of H2O.
