In the titration of an unknown acid, assume a chemist uses a solution of NaOH that has been sitting on the shelf for a long time and partially neutralized by the dissolved CO2 in the air. The concentration label on the bottle overestimates the NaOH concentration. How would this error affect the calculated concentration of the unknown acid

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

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .
