SUMMARY
The total electric charge of all electrons in a 50kg sample of water can be calculated using the atomic numbers and molar mass of its constituent elements, hydrogen and oxygen. Hydrogen has an atomic number of 1 and oxygen has an atomic number of 8. The molar mass of water (H2O) is 18 grams/mol, and Avogadro's number (N_A) is 6.02 x 1023 mol-1. By determining the number of moles in 50kg of water and multiplying by the total number of electrons, one can derive the total electric charge.
