Question
Map deb pling A researcher suspects that the pressure gauge on a 54.3-L gas cylinder containing nitric oxide is broken. An empty gas cylinder weighs 90.0 lb. The weight ofthe partially full cylinder is 118.9 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 How many moles of nitric oxide, NO, are in the cylinder? Number moles NO What is Videal for nitric oxide? Number What is the reduced temperature of the gas? Number (Scroll down for more questions.)Explanation / Answer
1)weight of gas=118.9-90=28.9lb
Molecular wt of NO=0.066lb/mole =>so moles of NO=weight/M.wt=28.9/0.066=437.878 moles
