Physics 12.27, how many moles of gas, one of my final questions!

Question

A gas with an initial temperature of 840 degrees Celsius undergoes the process shown in the figure. I can't upload the image so its an Isobaric graph that is constant at 3 atm. the initial volume is 300cm^3 and final is 100cm^3. The final temp is 370K. how many moles are there?? Please help me, thank you

Answer 1

You have been posting your entire final exam for other people to do for you. Do you quite understand that the purpose of a final exam is to determine whether YOU and not some morons on a web board can solve these problems? You're a filthy disgusting little cheater if you think that this is okay.

Answer 2

Use the formula PV = nRT to solve for the number of moles.

Make sure you convert cubic centimeters into cubic meters and degrees Celsius into degrees Kelvin. Oh, and convert atm into Pascals.
