A fire extinguisher is filled with pressurized gases such as Nitrogen, Carbon Dioxide, and a fluorocarbon (such as CF2ClBr). If the partial pressure of Nitrogen is 3.6atm, the partial pressure of Carbon Dioxide is 5.7atm, and the pressure of the fluorcarbon is 0.2 atm, what is the total pressure inside the fire extinguisher?
