Step-by-step working
The formula
n = CV
m = nM = CVM
| Symbol | Meaning |
|---|---|
| V | Final solution volume after making up to the calibration mark. |
| M | Molar mass of the weighed solute. |
When to use this calculator
The calculation gives the target mass. Laboratory preparation still requires suitable weighing, quantitative transfer, dissolution and making up to the mark.
Worked example
The page opens with these example values. The result below is pre-generated for reference.
- V = 250 cm³ = 0.25 dm³
- n = CV = 0.1 × 0.25 = 0.025 mol
- m = nM = 0.025 × 58.44 = 1.461 g
1.461 g
Common mistakes
- Use the final solution volume, not the initial water volume.
- Account for hydrate formula or purity if the substance used differs from the assumed formula.
