Show your work in your notebook. 2. Using the equation of the line you determined, calculate the exact volume of added titrant at the equivalence point. Show your work in your notebook. 3. Determine the concentration of ferrous ammonium sulfate in solution. Show your calculation in your lab notebook.

a is the answer to this question

explanation:

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
