Moles To Liters Formula
The following formula is used to calculate the volume in liters from the amount of a substance measured in moles.
Variables:
- V is the volume in liters (L)
- n is the amount of gas in moles (mol); R = 8.31446261815324 kPa·L/(mol·K), T is temperature in kelvin, and P is absolute pressure in kPa.
For an ideal gas, calculate V = nRT/P. At legacy STP (0 °C, 1 atm), the molar volume is approximately 22.41397 L/mol, often rounded to 22.4. At IUPAC STP (0 °C, 100 kPa), it is approximately 22.710955 L/mol. Real gases may differ.

What is Moles To Liters?
For a gas, moles can be converted to an estimated volume using a specified temperature and absolute pressure. This calculator uses the ideal-gas law; it does not determine liquid or solid volume from moles alone. For a solution, choose the molarity option and enter mol/L. Choose the stated STP convention or supply custom gas conditions.
How to Calculate Moles To Liters?
The following steps use the ideal-gas formula V = nRT/P.
- First, determine the amount of substance measured in moles (n).
- Next, choose gas conditions or enter temperature and absolute pressure, then use V = nRT/P to calculate liters.
- Finally, calculate the Moles To Liters.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
Amount of gas (n) = 3 mol. At legacy STP (0 °C, 1 atm), the ideal-gas estimate is approximately 67.241909 L.
