A chemist has a 100-gram sample of a compound that contains 17.096 grams of carbon, 2.186 grams of hydrogen, 10.844 grams of oxygen, 8.544 grams of nitrogen, 28.8618 grams of chlorine and 32.495 grams of bromine. What is the empirical formula of the compound?

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
