4. 1Why do pressure calculations come out the same for compounds with different molar masses? A molar mass is part of PV = nRT B they aren't, mass of molecules matters C lighter molecules hit side of container more often than heavier molecules, resulting in their exerting the same amount of pressure on the inside of the container D pressure of all gases is constant and doesn't change

5. 2If you have 1 mol ea of 5 different compounds, how much more pressure (P) will the 5 exert together than only one? A 2 times more P B 5 times more P C this cannot be determined with gas laws D 3 times more P
