Solution density at 20°C (d²⁰) :

**Density calculator and concentration converter**
Aqueous solutions of:
NaOH, KOH, NH_3(aq), Ca(OH)₂, HCl, HNO₃, H₂SO₄, H₃PO₄, CH₃COOH, NH₄Cl, NH₄NO₃, (NH₄)₂SO₄
C [mol/dm³]		x_w [-] mass frac.	x_m [-] molar frac.
	d [g/cm³]

Period "." or comma "," may be used as decimal point ("2.1" or "2,2" etc.). Any input with percent sign "%" will be recalculated into fraction (2% -> 0.02).

Check below if concentration range is within fitted data range

Select Salt/Base/Acid,
Enter concentration [mol/dm³], molar fraction or mass (weight) fraction,
Press appropriate [Calc] button,
Read approximate Density [g/cm³],
Read other approximate concentrations (C_m <-> x_w <-> x_m conversions),
Due to limited precision of fitted approximations, calculation cycles (like: C[mol/dm³] -> density -> weight frac. x_w -> C[mol/dm³] ) 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).
