**Solution density at 20°C** (d^{20}) :

- Select
**Salt/Base/Acid**, - Enter
**concentration**[mol/dm^{3}],**molar fraction**or**mass (weight) fraction**, - Press appropriate
**[Calc]**button, - Read approximate
**Density**[g/cm^{3}],

- Read other approximate
**concentrations**(C_{m}<-> x_{w}<-> x_{m}conversions),

Due to limited precision of fitted approximations, calculation cycles (like: C[mol/dm^{3}] -> density -> weight frac. x_{w}-> C[mol/dm^{3}] ) may change initial concentration values. - You may
**select/copy Summary/Info fields**(then e.g. paste to Excel, convert to columns and make a density graph). - Density value cannot be used to calculate concentration (d ->C may be ambiguous).
