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.
