Question

What is total positive or negative charge in a cup of 250g of H2O?

Answer 1

Answer:

250 ml = 250 gram of water since its density is 1 in cgs. One molecule of water has 2 hydrogen atoms (2 protons) and one oxygen atom (8 protons). So 250 g water will have 10 x 8.36 x 1024 = 8.36 x 1025 protons. So one cup of water has 13.3 mega coulomb positive and negative charge, so that the overall charge is zero Hope it will help you
