You blow up an ordinary party balloon with air until it has a diameter of 5.5 inches. Your friend blows up another balloon with helium gas until it has a diameter of 11 inches. Air consists mostly of O2 and N2 molecules, while helium gas consists of He atoms. Assume the pressure in each balloon is the same. What is the ratio the number of helium atoms to the total number of O2 and N2 molecules?
