Homework Help: Ideal gas law error

  1. Oct 27, 2007 #1
    1. The problem statement, all variables and given/known data
    A gas at 293.15 degrees kelvin and atmospheric pressure is compressed to a volume one fifteenth as large as its original volume and absolute pressure of 3000kPa. What is the new temperature of the gas?

    2. Relevant equations

    3. The attempt at a solution
    if i rearrange the equation above for t2 i get t2=101/293.15 x 3000 x 1/15= 1.722x10-3

    if i do it the wrong way and flip the divisions around so that t2=293.15 x 3000 x 1/15/101 =580.49

    i take the 580 - 273 =307

    307 is the right answer. perhaps i am doing it the right way, i just dont understand how this could be correct
    please explain this to me
