Ideal gas moles calculator
Estimate moles from pressure (atm), volume (L), and temperature (K) using PV = nRT.
Calculator
How to use
Ideal gas moles
$$PV = nRT$$
This calculator uses P in atm, V in liters, and T in kelvin, converting internally to SI.
- Assumes ideal gas behavior (low pressure, moderate conditions).
- Real gases deviate near condensation or high pressure.
When to use
- Stoichiometry with a gas volume at known P and T.
- Quick classroom estimates for lab gases.
