Atank contains 12.0 g of chlorine gas (cl2) at a temperature of 81 °c and an absolute pressure of 5.90 × 10^5 pa. the mass per mole of cl2 is 70.9 g/mol.
(a) determine the volume of the tank.
(b) later, the temperature of the tank has dropped to 29 °c and, due to a leak, the pressure has dropped to 2.60 × 10^5 pa. how many grams of chlorine gas has leaked out of the tank?

what are the choices?

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
