Are ideal gases the same as noble gases? Can you supply a picture of your homework please, or one of your problems? I believe that I can help :)

Edit: I also found this on ideal gases, but this is physics.... maybe this will help? https://www.khanacademy.org/science/physics/thermodynamics/temp-kinetic-theory-ideal-gas-law/a/what-is-the-ideal-gas-law#:~:text=The%20term%20ideal%20gas%20refers,the%20walls%20of%20the%20container.

Yeah, I don't think I've gotten deep enough to help you with that.... maybe you can use the masses on the periodic table to determine how many moles/atoms are in each gram amount, and then use that to solve the problem?

Sorry....

The thing is I've tried that and I still get it wrong😑
