I have mol% of a gas sample I also have temp and pressure when the sample was taken. How do I get % by volume? (L) [![data](https://i.stack.imgur.com/owJbR.jpg)](https://i.stack.imgur.com/owJbR.jpg)




Mol% and % by volume should be the same, assuming ideal gas behavior. For example, a sample containing 11.2 liters (1/2 mole) of hydrogen and 11.2 liters (1/2 mole) of methane should be 50 mol% hydrogen and 50 mol% methane, as well as 50% hydrogen by volume and 50% methane by volume. Note that by weight, the percentages of the components are no longer 50-50.
