A researcher suspects that the pressure gauge on a 49.9-L gas cylinder containing nitric oxide is broken. An empty gas cylinder weighs 135 lb. The weight of the partially full cylinder is 149.6 lb. This cylinder is located in a relatively chilly service hallway at 287 K. Follow the steps below to use the compressibility charts to estimate the pressure of the gas and the reading that the pressure gague should have. 1) How many moles of nitric oxide, NO, are in the cylinder? 2) what is the Vr(Ideal) for nitric oxide? 3) what is the reduced temperature of the gas? 4) What is the reduced pressure of the gas? 5) What is the pressure inside the gas cylinder? (Absolute Pressure) 6) What should the pressure gauge read?
