Solution Steps

Step 1: Write the Balanced Chemical Equation

The balanced chemical equation for the reaction is: \[ 3 \mathrm{NaOH} + \mathrm{H}_{3} \mathrm{PO}_{4} \rightarrow 3 \mathrm{H}_{2} \mathrm{O} + \mathrm{Na}_{3} \mathrm{PO}_{4} \]

Step 2: Identify the Mole Ratio

From the balanced equation, the mole ratio of \(\mathrm{H}_{3} \mathrm{PO}_{4}\) to \(\mathrm{Na}_{3} \mathrm{PO}_{4}\) is 1:1.

Step 3: Calculate the Moles of \(\mathrm{Na}_{3} \mathrm{PO}_{4}\) Formed

Given that we have 9.0 moles of \(\mathrm{H}_{3} \mathrm{PO}_{4}\), and using the 1:1 mole ratio, the moles of \(\mathrm{Na}_{3} \mathrm{PO}_{4}\) formed will be the same as the moles of \(\mathrm{H}_{3} \mathrm{PO}_{4}\).

\[ \text{Moles of } \mathrm{Na}_{3} \mathrm{PO}_{4} = 9.0 \text{ moles} \]

Final Answer

\[ \boxed{9.0 \text{ moles of } \mathrm{Na}_{3} \mathrm{PO}_{4}} \]
