How to use the molar conductivity calculator
Find the molar conductivity of an electrolyte from its measured conductivity and concentration. Enter conductivity, concentration in the fields above; the molar conductivity are computed instantly and plotted on the chart so you can see how the answer changes.
Common searches this calculator answers include “molar conductivity”, “electrolyte conductivity per mole”, “S cm² per mol”, “calculate molar conductivity”, “find molar conductivity”.
Formula
Variables
- kappa — Conductivity (S/m)
- C — Concentration (mol/m³)
Worked example
With conductivity = 0.0126 S/m, concentration = 100 mol/m³, the calculator gives molar conductivity ≈ 0.000126 S·m²/mol; molar conductivity ≈ 1.26 S·cm²/mol.
Frequently asked questions
What is the molar conductivity calculator used for?
Find the molar conductivity of an electrolyte from its measured conductivity and concentration. It helps with questions such as “molar conductivity”, “electrolyte conductivity per mole”, “S cm² per mol”.
What is the formula for the molar conductivity calculation?
Molar conductivity (S·m²/mol) = kappa / C. Molar conductivity (S·cm²/mol) = [Molar conductivity] × 1e4. Here kappa is conductivity (S/m), C is concentration (mol/m³).
What inputs do I need for the molar conductivity calculator?
You need conductivity in S/m, concentration in mol/m³. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the molar conductivity calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the molar conductivity result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
