"tyvm - only u made one mistake by putting 0 instead of E for power"
Response Details:
H atom has one electron, and O atom has 8 electrons.  Each H2O molecule has 10 electrons.

In 1.0 kg of H2O, there are	 (6.021023 molecules/mol) = 3.341025 molecules,

So the total charge = 10(-1.6010-19 C)(3.341025) = .
