009 10.0 points A metal bulb is filled with 10.2 g of CHCl3 and 0.322 g of CH4 (two gases). What is the total pressure in the bulb if the temperature is 345◦C and the volume is 50.0 mL? 1. 192 atm 2. 1450 atm 3. 12,030 atm 4. 0.107 atm 5. 12.1 atm 6. 107 atm 7. There is no pressure because the metal bulb exerts more force than the gas does.
