Im not sure how to calculate this

Transcribed Image Text:**Question:**
What is the concentration of lithium ions in 0.215 M Li₂SO₄?
**Explanation:**
- Li₂SO₄ dissociates into 2 Li⁺ ions and 1 SO₄²⁻ ion.
- Therefore, the concentration of lithium ions (Li⁺) is twice the molarity of Li₂SO₄.
**Calculation:**
Given:
- Molarity of Li₂SO₄ = 0.215 M
Concentration of Li⁺ ions = 2 x 0.215 M = 0.430 M
The result, displayed on the calculator, is 2 M, indicating that the correct concentration of lithium ions should be 0.430 M for this scenario.
