Olympic cyclists fill their tires with helium to make them lighter. Assume the volume of the tire is 860 mL, that is filled to a total pressure of 120 psi, and that the temperature is 26°C. Also assume an average molar mass for air of 28.8 g/mol. Calculate the mass of the air in an air-filled tire? Calculate the mass of helium in a helium-filled tire? What is the mass difference between the two?
