Molar Volume Calculator — Vₘ = V/n

Molar volume — liters per mole — is the most practical form of the gas laws for bench work. At STP (0 °C, 1 atm) it is 22.414 L/mol; everywhere else it follows V/n directly.

How to interpret the result

Worked check: 22.414 liter of gas containing 1.000 mole at STP → V_m = 22.414 L/mol. For other conditions use RT/P instead of the STP shortcut.

V_m is condition-specific — always note the T and P it refers to
