Question
**Chemical Reaction Problem**

Calculate the mass of precipitate (in grams) formed when 20.5 mL of 0.300 M Ni(NO₃)₂ reacts with 16.0 mL of 0.300 M NaOH in the following chemical reaction:

\[ \text{Ni(NO}_3\text{)}_2\text{(aq) + 2 NaOH(aq)} \rightarrow \text{Ni(OH)}_2\text{(s) + 2 NaNO}_3\text{(aq)} \]

**Instructions for Calculation:**

1. Determine the moles of each reactant:
   - Use the formula: \(\text{Moles} = \text{Molarity} \times \text{Volume (L)}\).

2. Identify the limiting reactant:
   - Compare the mole ratio from the balanced equation to the moles calculated.

3. Calculate the moles of \(\text{Ni(OH)}_2\) formed.

4. Convert moles of \(\text{Ni(OH)}_2\) into grams:
   - Use the molar mass of \(\text{Ni(OH)}_2\) for the conversion.
