Water is H2O. Each hydrogen atom contains on electron and each water molecule contains 2 hydrogens. Each oxygen contains 8 electrons. We can find out how many grams of water there are in 1 cup of water. The molecular weight of water is 18 grams per mole. We can find out how many moles of water are in the cup and therefore the number of electrons and protons.
