Homework Help: Total charge of electrons in 1.77 Kg of H20

  1. Mar 22, 2010 #1
    1. The problem statement, all variables and given/known data
    What is the total charge of all the electrons in 1.77 Kg of H20?

    2. Relevant equations
    I really just lost on how to do this problem as I missed school today. Any help would be greatly appreciated

    3. The attempt at a solution

    the 1st step I took was trying to find the total number of electrons and got 1.943E30 but this is probably wrong.
