Three bulbs are connected by tubing, and the tubing is evacuated. The volume of the tubing is 32.0 mL. The first bulb has a volume of 35.0 mL and contains 3.00 atm of argon, the second bulb has a volume of 250 mL and contains 2.27 atm of neon, and the third bulb has a volume of 33.0 mL and contains 6.44 atm of hydrogen. If the stopcocks (valves) that isolate all three bulbs are opened, what is the final pressure of the whole system in atm?
