Answer:
1.38 × 10²⁰ zinc ions
Explanation:
Step 1: Given data
Moles of Zn²⁺: 2.29 × 10⁻⁴ mol
Step 2: Convert 2.29 × 10⁻⁴ moles to ions
To convert moles to ions, we need a conversion factor: Avogadro's number. There are 6.02 × 10²³ Zn²⁺ ions in 1 mole of Zn²⁺ ions.
2.29 × 10⁻⁴ mol × 6.02 × 10²³ ions/1 mol = 1.38 × 10²⁰ ions
