Question

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 164.2 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 reduced temperature of the gas?
3.What is the reduced pressure of the gas?
4.What is the pressure inside the gas cylinder (absolute pressure)?
5. What should the pressure gauge read?

Explanation / Answer

76

At a constant temperature, the volume and the pressure are inversely proportional, that it, the greater the volume, the lesser the pressure on the gas, and viceversa.
