A balloon containing equal moles of helium gas and oxygen gas had a small leak and gas began to slowly effuse out of the balloon. After allowing the gas to escape for 30 seconds, the hole is sealed. Which of the remaining gases, helium or oxygen gas, will be in higher concentration inside the balloon and why?
