A 15.0 atm pressurized 5.00 L cylinder refriegerated at 9.89°C is filled with an air mixture containing 30% helium, 30% diatomic nitrogen, and 40% nitrogen dioxide by volume. What is the partial pressure of each component and how many grams of each component are contained in the cylinder?

24. a sports ball is inflated to an internal pressure of 1.85 atm at room temperature (25 °c). if the ball is then played with outside where the temperature is 7.5 °c, what will be the new pressure of the ball? assume the ball does not change in volume nor does any air leak from the ball a) 0.555 atm b) 1.74 atm c) 1.85 atm d) 1.97 atm
