STP Calculator

Find gas volume at standard temperature and pressure.

Volume at STP 44.828

Formula: volume = moles × 22.414 L/mol

Step-by-step with your numbers:

1. Values used:

2. Moles of gas = 2 mol

4. Volume at STP = 44.828

Did we solve your problem today?

At standard temperature and pressure, one mole of any ideal gas fills 22.414 L.

The math behind it

volume = moles × 22.414 L/mol (STP = 0 °C, 1 atm).

2 mol → 44.83 L.

STP definition?

Classically 0 °C and 1 atm; IUPAC now uses 1 bar (≈22.711 L/mol).
