Question in gases
« on: November 12, 2020, 10:14:08 AM »
Hi,
I need help with a question.

This is what I tried:
https://pasteboard.co/JA213Ox.png

Generating gas (gas producer) is a type of gaseous fuel (gases whose combustion produces ceramic energy) which is produced by passing air or vapor through a layer of hot coal or another layer of flammable material extracted from coal. Such a gas has the following composition ( In volume percentages):


8.0% CO2, 23.2% CO, 17.7% H2, 1.1% CH4, 50% N2.


What is the density of gaseous fuel at 23 degrees Celsius and at a pressure of 763 mm Hg? (Answer must be given in units of gr / m3)?

You have to convert the ideal Gas Law that you get Rho =.

combine pV= nRT, n= m/ M and Rho = m/V.

I think your calculation sounds ok, even calculated percentage of mass.
