So, 100 g of water means= 100/18 moles of waterNow, 1 molecule of water contains 1x8 electron of Oxygen and 2x1 electron of Hydrogen= 10 electron per molecule.So total number of electron in 100 gram water =total molecule in 100 gram water x number of electron in each molecule= (100/18)×10 moles= 55.555 moles of electron= 55.555x6.022x10^23 numbers of electrons. Which is 334.5 × 10^23= 3.34×10^25 electrons.Now, q= ne. Hence charge on these electrons is 3.34×10^25 × 1.6×10^-19 Coulomb =-5.34×10^6 C.Nucleus consists of protons and proton too has magnitude of charge same as that on electron.Now apply coulombs law we get F= 1/4π€ ×q^2/r^2. Convert r in meters. U must now calculate on ur own without using log. On simplification9×10^9×28×10^12×10^-4.Calculate u will get it right....................,...... Hope it helps.Regards.Rohit.
