Solution Volume:1 L (1000 mL)
Color intensity and representative particle density are visual concentration aids. Real microscopic solutions contain billions of trillions of solvated ions.
📐Step-by-Step Mathematical Derivation
Given ➔ Formula ➔ Solve1. Given Quantities:
• Solute: Copper(II) Sulfate (CuSO₄)
• Solute Amount (n): 0.5 mol (79.81 g)
• Solution Volume (V): 1 L (1000 mL)
2. Governing Formula:
Molarity (M) = n / V [mol / L]
3. Substitute Values:
M = 0.5 mol / 1 L
4. Calculated Result:
M = 0.5 M (mol/L)
5. Chemical Interpretation:Every 1.0 Liter of this solution contains exactly 0.5 moles of dissolved CuSO₄.
🧠Key Insight
Molarity depends on the ratio of solute particles to solution volume.
If you double the moles while simultaneously doubling the volume, the molarity remains strictly identical!
