How to use the gas volume at stp calculator
Convert moles of gas to volume at standard conditions. Enter amount of gas in the field above; the volume at stp (0 °c, 1 atm), volume at satp (25 °c, 1 bar) are computed instantly and plotted on the chart so you can see how the answer changes.
Formula
Variables
- n — Amount of gas (mol)
Worked example
With amount of gas = 2 mol, the calculator gives volume at stp (0 °c, 1 atm) ≈ 44.828 L; volume at satp (25 °c, 1 bar) ≈ 49.578 L.
Frequently asked questions
What is the formula for the gas volume at stp calculation?
Volume at STP (0 °C, 1 atm) (L) = n × 22.414. Volume at SATP (25 °C, 1 bar) (L) = n × 24.789. Here n is amount of gas (mol).
What inputs do I need for the gas volume at stp calculator?
You need amount of gas in mol. 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.
