Use a graduated cylinder to add
approximately 40 mL of water to the
calorimeter. Measure the mass of the
calorimeter (no lid) and water to the
nearest 0.01 g.

52.31

The other person was wrong. If you did the lab on the side it would show you that 52.31 is the answer

Have a good day luvs

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
