13.2. A blimp rises because it is filled with Helium gas which has a smaller molecular mass than air (in g/mol). Helium can lift objects because it exhibits a buoyant force equal to the difference in the grams per mole. At room conditions (P=1atm, T=25C), what volume of helium would lift a person who weighs 195 pounds? Show your work in calculations.
