100% correct as well.

Avogadro's Law - Equal volumes of gases under the same conditions of temperature and pressure contain the same number of molecules.

Avogadro's Constant - (6.022045 � 0.000031)x10^23
6.0x10^23

[Fiach] If you really want to confuse some folks, just tell them that if you combine 2 mols of H2 with 1 mol of O2, you get only 2 mols of H2O.

BTW: scored 100%. However, I had to think about the Gas question a bit though. I eventually remembered PV=nRT bit. It's been awhile since I had chem.

Hehe...got 100% correct, and also had a bit of trouble with the gas equation. I forgot all about PV=nRT...but I figured out the relative molecular weights of the two molecules, realized they weren't any sort of nice ratio, so the answer had to be 10 liters

Kelly - that's exactly what I did; I eliminated all the other answers. 10 liters was the only logical choice.
