17:15 uh sir, i was thinking that since H2, O2 and N2's molecule size is different from eachother, bigger molecule should take more space, means there should not be exact same number of molecules in same balloon e.g. if we put marble sized balls into a 1x1x1 meter cube, many can be contained into it due to their small size. but in same size box if we put a table tennis size ball e won't be able to put exactly same number of Ping pongs as that or marbles in short the number cannot be exactly 6.022x 10^23 molecules in all balloons. correct me if I'm wrong regards
