"Universal" Gas Constant(/s)
I'm having a bit of trouble with the ideal gas law's universal constant(/s). If it's so universal, then why are there 3 numbers? And when do you use each one?
On my notes, it says that the universal gas constants are .0821 (labled "atm"), 62.4 (labeled "moles") and 8.314, which is not labeled at all.
I'm guessing that each number is used when trying to find the amount of atms, moles or whatever it may be. and What's the third no. for? The temperature in Kelvin?
P.S. I need to study for a chemistry test/quiz that my teacher is going to give us (The General Chemistry Class) tomorrow. If someone could give me some help/review and problems dealing with Charles' law, Boyle's law, Gay-Lussac's Law (My teacher pronounces the name Gay-Lou-Sack. Is this correct?Or is it more like :"Gie lussahk"?) The Combined Gas Law, the Ideal Gas Law, and Dalton's Law of Partial Pressures, that would be great. If you don't want to do the review, then just throw me some problems. (Save for the Ideal Gas Law- I need help with that.)
