How do I solve the following problem?
### Precipitation Reaction Problem

#### Problem Statement:
If a solution containing 52.61 g of lead(II) nitrate is allowed to react completely with a solution containing 7.410 g of sodium sulfide, how many grams of solid precipitate will be formed?

1. **Mass of solid precipitate:** _______________ g

2. **How many grams of the reactant in excess will remain after the reaction?**

    **Mass of excess reactant:** _______________ g

3. **Assuming complete precipitation, how many moles of each ion remain in solution? If an ion is no longer in solution, enter a zero (0) for the number of moles.**

    **Pb²⁺:** _______________ mol

#### Instructions:
- Calculate the mass of the solid precipitate formed using stoichiometry.
- Determine which reactant is in excess and calculate its remaining mass after the reaction.
- Calculate the moles of each ion remaining in the solution after the reaction is complete.

##### Contextual Note:
This is a classic stoichiometry problem commonly encountered in general chemistry courses. It involves the concepts of limiting reactants, excess reactants, and stoichiometric calculations to determine the amounts of products and remaining reactants.
