![**Stoichiometry Calculation: Determining Moles in a Reaction**
**Problem Statement:**
Given the chemical reaction:
\[ \text{Pb(NO}_3\text{)}_2\text{(aq) + K}_3\text{PO}_4\text{(aq) → Pb}_3\text{(PO}_4\text{)}_2\text{(s) + KNO}_3\text{(aq)} \]
Calculate the moles of \(\text{Pb(NO}_3\text{)}_2\) required to produce 415 grams of \(\text{Pb}_3\text{(PO}_4\text{)}_2\).
**Instructions:**
1. **Determine the molar mass** of \(\text{Pb}_3\text{(PO}_4\text{)}_2\).
2. **Convert grams to moles** using the formula:
\[
\text{Moles} = \frac{\text{Grams}}{\text{Molar Mass}}
\]
3. **Use the stoichiometry** of the balanced equation to find the moles of \(\text{Pb(NO}_3\text{)}_2\) needed.
**Interface Description:**
- A numeric keypad is provided for input, with options for clearing entries (C) and multiplying by ten (×10).
- Ensure all calculations follow the stoichiometric relations dictated by the balanced chemical equation.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4677afa7-7a4c-4c77-9fe0-7a7fa397f8cf%2F6e73591b-ee0e-489d-85fe-3e32bb2b2f3d%2F72k9tcw_processed.jpeg&w=3840&q=75)
