liters of air ?
« on: August 22, 2004, 05:28:37 PM »

    How many liters of air at 25 degrees and 1.00 atm could be stored in a 10.00-L high-pressure air tank if compressed to 25 degrees and 175 atm?

 i'm not sure how to start this, i've never seen an ex. like this either, please help if you can . thank you so much. :-*

I think that's low enough pressure that the ideal gas law is still a pretty good approximation, so you can use that.

PV = nRT can arranged into PV/T = nR [constant] since n (no. of moles of gas) is fixed and R is the molar gas constant.

Use P1V1/T1 = P2V2/T2 to express the 2 different condition to get your answer
