Question:

If it takes 3.52 s for 10.0 mL of helium to effuse through a hole in a container at a particular temperature and pressure, how long would it take for 10.0 mL of oxygen, O2, to effuse from the same container at the same temperature and pressure? (The rate of effusion can be given in terms of volume of gas effused per second.)
