liter of hydrogen
Forum rules
Dear convert-me.com forum visitors,
Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.
All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page
Thank you for being with us and sorry for any inconveniences this could caused.

Depends on how much hydrogen is in there.
Either mass (grams, kilograms, etc) or number of moles is a way to refer to a definite amount of hydrogen (or any gas). Hydrogen is an a diatomic molecule with a molecular weight (rounded) of 2 amu, so a mole weighs 2 grams.
The volume of a gas does not define the amount unless temperature and pressure are specified. They are related by the ideal gas equation PV = nRT, where n is number of moles and R is the gas constant. At 1 atm, and 0 degrees C, 1 mole of ideal gas (and most real gases approximate it well) occupies 22.4 L.
