A sample of N2 gas was placed in a flexible 9.0L container at 300K at a pressure of 1.5atm. The container was compressed to a volume of 3.0L and heat was added until the temperature reached 600K. The new pressure inside
the container is
atm.

i'm pretty sure its b i might be wrong though!

i would say b

explanation:

but i think i would need more information than that

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
