    You would have to use the ideal gas law: PV = nRT where,

    P = pressure

    V = volume

    n = moles

    R = universal gas constant for a specific pressure (in this case it's 62.364 torr)

    T = temperature in Kelvin

    First, convert Celsius to kelvin by adding 273 to 25, which gives you 298K

    Now plug in your variables to find n:

    (800 torr) (1.25 L) = n (62.364) (298K)

    1000 = 18584.472n

    Now divide 1000 by 18584.472 to get n:

    1000/18584.472 = 0.054 moles
