A researcher suspects that the pressure gauge on a 49.9 L49.9 L gas cylinder containing nitric oxide is broken. An empty gas cylinder weighs 135 lb.135 lb. The weight of the partially full cylinder is 153.2 lb.153.2 lb. This cylinder is located in a relatively chilly service hallway at 287 K.287 K. Follow the steps below to use the compressibility charts to estimate the pressure of the gas and the reading that the pressure gauge should have.

How many moles of nitric oxide, NO,NO, are in the cylinder?

moles of NO:NO:

mol
