1. The problem statement, all variables and given/known data When do you use 1 mol = 22.4 L and 1 mol = 24 L? I have a test coming up and would like to clarify this. 2. Relevant equations 3. The attempt at a solution I know that 1 mol = 22.4 L of any ideal gas at STP mean 1atm at (273K) I understand this. But what about 1 mol = 24 L. Would I use this as a conversion factor is STP or ideal gas is not mentioned? I found out that the 24 L in 1 mol is for room temperature. Can anyone check my information? Am I correct? If not not can you please explain thank you.
