Gas Law Chemistry

I need help on these two questions:

If a certain gas occupies a volume of 16L when the applied pressure is 8.0atm , find the pressure when the gas occupies a volume of 4.0L .

A certain gas is present in a 12.0L cylinder at 4.0atm pressure. If the pressure is increased to 8.0atm the volume of the gas decreases to 6.0L . Find the two constants k1, the initial value of k, and kf, the final value of k, to verify whether the gas obeys Boyle’s law.

  1. #1.
    P1V1 = P2V2

    #2.
    P1V1 = k1
    P2V2 = k2
