![**Practice Assignment: Stoichiometry**
On a separate sheet of paper, show the setup and answer for each problem. Follow the formal problem-solving method that is illustrated in the examples above.
For problems (1-7), use the equation:
\[ 3 \text{NaHCO}_3 + \text{H}_3\text{PO}_4 \rightarrow 3 \text{CO}_2 + 3 \text{H}_2\text{O} + \text{Na}_3\text{PO}_4 \]
1. Number of moles of CO₂ produced from **5.0 moles** of H₃PO₄.
2. The number of grams of CO₂ formed from **3.0 moles** of NaHCO₃.
3. The number of grams of NaHCO₃ needed to produce **6.80 moles** of water.
4. Grams of CO₂ resulting when **49.0 g** of H₃PO₄ reacts.
5. What mass of NaHCO₃ reacts in order to produce **450. g** of Na₃PO₄?
6. Calculate the percent yield of Na₃PO₄ if **350. g** of Na₃PO₄ are formed from **692 g** of NaHCO₃.
