The total positive charge of all the protons in 1.0 mol of water is $~9.64\times 10^5~C$
One water molecule consists of two hydrogen atoms and one oxygen atom. The number of protons is $2+8$ which is 10 protons. Each proton has a charge of $1.6\times 10^{-19}~C$ We can find the total positive charge of all the protons in 1.0 mol of water: $q = (6.022\times 10^{23})(10)(1.6\times 10^{-19}~C)$ $q = 9.64\times 10^5~C$ The total positive charge of all the protons in 1.0 mol of water is $~9.64\times 10^5~C$.
