How to use the henry's law gas solubility calculator
Find dissolved gas concentration from pressure. Enter henry constant, partial pressure in the fields above; the dissolved concentration is computed instantly and plotted on the chart so you can see how the answer changes.
Formula
Variables
- kH — Henry constant (mol/(L·atm))
- P — Partial pressure (atm)
Worked example
With henry constant = CO2 (25 °C), partial pressure = 1 atm, the calculator gives dissolved concentration ≈ 0.034 mol/L.
Frequently asked questions
What is the formula for the henry's law gas solubility calculation?
Dissolved concentration (mol/L) = kH × P. Here kH is henry constant (mol/(L·atm)), P is partial pressure (atm).
What inputs do I need for the henry's law gas solubility calculator?
You need henry constant in mol/(L·atm), partial pressure in atm. 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 this 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 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.
