In an experiment, 1.75 g sample of acetic acid, ch3cooh, was burned in oxygen in a calorimeter. the calorimeter contained 925g of water and had a heat capacity of 2.53 kj/°c. the temperature of the calorimeter and its contents increased from 22.2°c to 26.5°c. use these data to determine the molar heat of combustion of acetic acid? (specific heat capacity of water = 4.18 kj/kg·°c) show all work

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
