    At a constant temperature and number of moles of the gas the product of PV is equal to some constant. At another set of condition of temperature, the constant is still the same. Calculations are as follows:

    P1V1 = P2V2

    P2 = P1 x V1 / V2

    P2 = 1 x. 450 / 2

    P2 =.225 atm

    Hope this answers the question. Have a nice day.
