    Suppose a cup is of volume= 250 cm3 Mass of water = 250 g Molar mass of eater = 18g No. Of molecules in18 g= 6.023 × 10-23 No. Of molecules in 1 g= 6.023× 10-23/18 1 molecle of H2O contains= 10 e- So, 6.023×10-23× 10/18 So u will be able to get the answer

    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
