**Problem Statement:**

What mass of precipitate (in grams) is formed when 20.5 mL of 0.800 M Co(NO₃)₂ reacts with 16.5 mL of 0.800 M NaOH in the following chemical reaction?

**Chemical Reaction:**

Co(NO₃)₂(aq) + 2 NaOH(aq) ⟶ Co(OH)₂(s) + 2 NaNO₃(aq)

---

**Explanation:**

This problem involves a precipitation reaction where cobalt(II) nitrate reacts with sodium hydroxide to form cobalt(II) hydroxide as a solid precipitate and sodium nitrate in solution. To find the mass of the precipitate formed, follow these steps:

1. **Calculate Moles of Reactants:**
   - **Co(NO₃)₂:** Use the formula \( \text{Moles} = \text{Volume (L)} \times \text{Molarity (M)} \).
   - **NaOH:** Similarly, calculate using the same formula.

2. **Determine Limiting Reagent:**
   - Compare the mole ratio from the balanced equation to find which reactant is the limiting reagent.

3. **Calculate Moles of Precipitate:**
   - Based on the limiting reagent, use stoichiometry to find moles of Co(OH)₂ formed.

4. **Find Mass of Precipitate:**
   - Convert moles of Co(OH)₂ to mass using its molar mass.

This process outlines how to solve for the mass of precipitate using stoichiometry and reactant quantities in a chemical reaction.
