Electron charge in 1Kg of H2O

  1. Oct 20, 2004 #1
    what is the total electron change in 1 kg of H2O?

    well I know I can solve this one by myself but that would take me some hours to figure out what to do so it's probably less cluttering and memorizing wrong things if I post it here

    I know an electron has a charge of -1.6x10^-19C
    I know an H2O molecule is neutral, so has the same number of electrons and protons

    what I don't know is how to figure out how many electrons there are in 1kg of H2O, or if I even need to know that.

    Find the number of electrons in one molecule of water. Then calculate the number of molecules in one kilogram of water using Avogadro number and mole concept.
