Question

Transcribed Image Text:**Problem Statement:**
Determine the mass of the precipitate (in grams) formed when 20.5 mL of 0.700 M Zn(NO₃)₂ reacts with 18.5 mL of 0.700 M NaOH in the given chemical reaction.
**Chemical Reaction:**
Zn(NO₃)₂(aq) + 2 NaOH(aq) → Zn(OH)₂(s) + 2 NaNO₃(aq)
**Explanation:**
- Zn(NO₃)₂ and NaOH are aqueous reactants.
- Zn(OH)₂ is the solid precipitate formed, while NaNO₃ remains in the aqueous solution.
- The stoichiometry shows a 1:2 ratio between Zn(NO₃)₂ and NaOH, indicating one mole of Zn(NO₃)₂ reacts with two moles of NaOH to form one mole of Zn(OH)₂ precipitate.
