Jason wants to use a Pilates ball as a desk chair. The Pilates ball has a diameter of 65cm, and is filled to a recommended air pressure of 0.9 PSI. What is the average force of the air inisde the Pilates ball pushing out? If the ball is filled with carbon dioxide (CO2) at 22 degrees C, how many molecules of CO2 are in the ball? (Area of a sphere = 4pir^2, Volume of a sphere = 4/3pir^3)
