does the mole ratio in this question affect the answer?
a 2:1 mixture of O3 and O2 is allowed to effuse through a pinhole in a balloon.after a few seconds, the content of the balloon is analyzed. what will be the mole ratio of the gases in the balloon?
yes, of course. See Graham's law of effusion. If the effusion rate is different for each compound, then for each compound the mole ratio will change. In this case, O2 will effuse faster, so the mole ratio will be greater than 2:1, as more O3 remains.
