At 30°C , 500cm^3 of H_2 at 0.52 atm pressure and 1 dm^3 of N_2 at 0.78 atm pressure are transferred into a 1500 cm^3 flask. Calculate the total pressure of the mixture of gases

i know that

i cannot understand the question

i have solved numericals related to dalton's law but this one is confusing me

  • Australopithecus
you would add both Poxygen + Pnitrogen = Ptotal I would assume

Find the pressure Hydrogen would have in the 1500[cm^3] volume \[p_1V_1=p_2V_2\\p_2=p_1\frac{V_1}{V_2}\]

  • anonymous
then why temperature and volumes are given ? there must be some reason
UnkleRhaukus
  • UnkleRhaukus
and similarly find the same for the nitrogen, then add these pressures together
Australopithecus
  • Australopithecus
Temperature is the same for both of the gases, so don't worry about it. You can find the moles of gas used from the pressures and volumes given
anonymous
  • anonymous
what is the V1 ....for hydrogen and nitrogen ?
Australopithecus
  • Australopithecus
You are given a final volume use that to figure out the new pressure of both gases
Australopithecus
  • Australopithecus
30 degrees C, 500cm^3 of H_2 at 0.52 atm -> use ideal gas law to find moles 30 degrees C, 1 dm^3 of N_2 at 0.78 atm -> use ideal gas law to find moles
anonymous
  • anonymous
so the 500 and 1 are useless ? ...the main volume is 1500 right ?
Australopithecus
  • Australopithecus
no they aren't useless you need that information to find the moles of the individual gases
anonymous
  • anonymous
okay first i have to find moles then ?
Australopithecus
  • Australopithecus
Yes of both gases Then once you have the moles you can use the equations, posted here, http://www.chm.davidson.edu/vce/gaslaws/daltonslaw.html Then just add both pressures if I'm not mistaken
anonymous
  • anonymous
why are we finding moles for ?
Australopithecus
  • Australopithecus
because you need to find them to figure out the pressure of each gas in the final volume
anonymous
  • anonymous
oh!!
anonymous
  • anonymous
i am doing it !! wait
anonymous
  • anonymous
how to find moles ?
Australopithecus
  • Australopithecus
Just use PV = nRT
Australopithecus
  • Australopithecus
assuming it acts like an ideal gas
anonymous
  • anonymous
oh !! i did'nt thought of that !!!
anonymous
  • anonymous
thanks

H_2 = 0.0104 moles
Australopithecus
  • Australopithecus
just use that website I posted, and add the pressures, I could be wrong though I'm not great a physical chemistry
Australopithecus
  • Australopithecus
at*

  • Australopithecus
These two gases aren't ideal, so you might want to look up how to calculate the moles of a non ideal gas
Australopithecus
  • Australopithecus
http://www.chm.davidson.edu/vce/gaslaws/daltonslaw.html This resource will help I think
Australopithecus
  • Australopithecus
If this is just an intro chem course though you can just use PV = nRT to solve this, by making the assumption that these gases act like ideal gasses (monoatomic gasses)
