### Chemistry Problem Example: Stoichiometry **Problem Statement:** 13) If 82 grams of Sodium Phosphate (Na₃PO₄) and 32 grams of Potassium Hydroxide (KOH) are allowed to react, how many grams of Sodium Hydroxide (NaOH) can be created? The unbalanced chemical equation for the reaction is: \[ \_\_\_\_\_ \text{Na}_3\text{PO}_4 + \_\_\_\_\_ \text{KOH} \rightarrow \_\_\_\_\_ \text{NaOH} + \_\_\_\_\_ \text{K}_3\text{PO}_4 \] **Options:** a) 10.5 grams b) 22.8 grams c) 36.9 grams d) 95.6 grams To solve this problem, you need to: 1. **Write the balanced chemical equation** for the reaction. 2. **Convert grams of the reactants** (Sodium Phosphate and Potassium Hydroxide) to moles using their molar masses. 3. **Use stoichiometry** to find the limiting reactant. 4. **Calculate the moles of Sodium Hydroxide** produced based on the limiting reactant. 5. **Convert the moles of Sodium Hydroxide** to grams. Please follow these steps systematically to find the correct answer.
