how is pressure not proportional to the number of moles?
Who says it's not?
Young and Freedman page 591-592 in the ideal gas equation section. The author does not seem to include the relationship between the number of moles and pressure.
For those of us who don't have the book handy.... What exactly do they say?
But... PV=nRT... So P is proportional to n, if you keep everything else stable...
