    Static Charges
    A person scuffing her feet on a wool rug on a dry day accumulates a net charge of -40.6 mC. How many excess electrons does this person get? By how much does her mass increase?
    first I used # of electrons aquired= given charge/ charge on one electron

    so # OF ELEC = 4.06*10^-6/ 1.6*10^-19= 2.5375*10^-25 but that wasn't right... so I don't know what to do...

    first, 40.6 mC is not

    second, , not , so you've typed something into your calculator wrong.

    Take these into mind and try again. I believe that your method is correct.
