Problem 1: A steel container is filled with 2 gram-mole of oxygen and 3 gram-moles of nitrogen. The volume of the container is V=20 liters and the temperature is T=27C. a) Calculate the pressure p inside the container. (2 points) b) Calculate the partial pressures pO2 and pN2 (3 points) c) If the container is vacuumed and re-filled with different amounts of oxygen and nitrogen. The partial pressure for oxygen is pO2=1.5atm and, and for nitrogen pN2=2.5atm. Calculate the a) The total pressure of the container (1 point) b) The moles of oxygen nO2 ( 2 points) c) The moles of nitrogen nN2 (2 points)
