Formula and explanation
Formula: n = (V)/(V m) Applicable Conditions: Applicable to ideal gases. Under standard temperature and pressure (STP, 0°C, 101.325 kPa), V m ≈ 22.4 L/mol. Explanation: This formula is used to calculate the amount of substance of a gas from its volume. V is the gas volume (unit: L), and V m is the molar volume of the gas (unit: L/mol).
