You have 0.6 kg of water. One mole of water has a mass of 18 g/mol and each molecule of water contains 10 electrons since water is H2O. What is the total electron charge contained in this volume of water? Answer in units for C.(adsbygoogle = window.adsbygoogle || []).push({});

First I converted 0.6 kg to 600 g. Then I divided that by 18 to get the number of moles, which was 33.3. Then I multiplied it by Avogadro's number to get the number of molecules and got 2.01 x 10^25. Then I multiplied it by the number of electrons, and got 2.01 x 10^26. Finally, I multiplied it by the electon charge, 1.602 x 10^-19, and got 3.21 x 10^7. This isn't right.

Am I going about this in the right way?
