Step-by-step working
The formula
n = CV
1 dm³ = 1000 cm³
| Symbol | Meaning |
|---|---|
| C | Molar concentration in mol dm⁻³. |
| V | Solution volume in dm³ in the equation. |
When to use this calculator
This relation counts amount of solute per final solution volume, not solvent volume added.
Worked example
The page opens with these example values. The result below is pre-generated for reference.
- V = 25 cm³ = 0.025 dm³
- C = n/V = 0.0025 / 0.025 = 0.1 mol dm⁻³
0.1 mol dm⁻³
Common mistakes
- 25 cm³ = 0.025 dm³, not 25 dm³.
