One mole of an ideal gas is sealed in a 22.4- container at a pressure of 1 and a temperature of 273 . The temperature is then increased to 305 , but the container does not expand. What will the new pressure be?

    If v is constant...

    P1/T1=P2/T2 Solve for P2.

  • chem - ,

    thank you. i tried doing that and i got 25.02, which is wrong, im not sure what im doing wrong..

  • chem - ,

    You are not using p1 as 1 atm, which is given. You put the volume in for P1.

  • chem - ,

    yes that is what i did i multiplied 22.4 times 305 divided by 273 and i got it wrong

  • chem - ,

    C,mon.
    P1 = 1
    T1 = 273 (I guess that K, you don't say).
    P2 = ??
    T2 = 305 Kelvin?
    Bob Pursley told you you can't use volume of 22.4 for pressure. Pressure is 1 in the problem.
