if there r two different gases in the same container with the same # of moles, do they have the same pressure?
like, H2 and O2 have the same # of moles. do they have the same pressure when they'r in the same container?

so if the pressure is 1 atm, is the pressure of H2 0.5atm and O2 0.5atm? does the size of the molecules matter?

The size of the molecules doesn't matter. Only the relative numbers of molecules matters.
If 50% of the gas molecules are O2, 50% of the gas molecules are H2, and the total pressure is 1 atm, then the partial pressure of each gas is 0.5 atm.

No, in an ideal gas situation, the molecule size doesn't matter. The mean free path that a molecule can travel in under conditions where the substances act as ideal gas is much larger than the molecular size.

no they don't have because they are diferrent in densities and volume....and actually when the 2 diff. gas were took place in the same container,the pressure loo like this------P1+P2=P
