Olympic cyclists fill their tires with helium to make them lighter. The mass of air used in the air filled tire is 8.56 g. Assume that the volume of the tire is 855 mL, that it is filled to a total pressure of 8.51 atm, and that the temperature is 25°C.
a. Calculate the mass of helium in a helium-filled tire. (you must show all work to earn full credit).
b. What is the difference between the two?
c. Why is the helium-filled tire lighter?
