Chemistry help please?

What is the resultant pressure if 3.4 mol of

ideal gas at 273 K and 1.93 atm in a closed

container of constant volume is heated to

614 K?

Answer in units of atm.

    P1/T1 = P2/T2

    1.93 atm / 273 K = P2 / 614 K

    P2 = 4.34 atm

    An easy way to remember the various Gas laws (Boyle's Law, Charles' Law, and Gay-Lussac's Law) is to remember one equation: PV = nRT (the Ideal Gas law).

    In your problem the volume is constant and the number of moles (n) is constant. R is a constant, so rearrangement yields P/T = nR/V. Since nR/V is constant then all values of P/T must equal the same constant: P1/T1 = P2/T2 = P3/T3. etc.
