I did an experiment measuring the volume of an air bubble [from atube submerged in water] at various temperatures, from 75C down to5C.
ex: at 75C the vol was 4.4mL, at 73C the vol was 4.2 mL, etc. - Irecorded the volume every 3 degrees down.
I will use [ ] for things that should be sub-script
I now need to find N[air]
I recorded the atmospheric pressure, P[air] as 29.83 torr; which is.039 atm
I know that n[air] =PV/RT
--> p = pressure, v=volume, r=.08206L, t=temp
However, I do not know how I am supposed to be able to use thisequation with the information I have? I have a whole list of tempsand volumes, am I supposed to take the average?
