  • Chemistry -

    9.09e-3 J/cm2

  • Chemistry -

    not right

  • Chemistry -

    no right

  • Chemistry -

    2.8*10^-4

  • Chemistry -

    how did you get that???

  • Chemistry -

    its wrong

  • Chemistry -

    cheat 3.091 x 10^-6 joules/cm2

  • Chemistry -

    It still wrong answer.

  • Chemistry -

    6.23 e -3 finally is correct

  • Chemistry -

    nop. still wrong
