Find the total positive charge of all the proton in 5gm of water

Number of moles in 5 gm of water is given as

1 mole consist of Avagadro number of molecules of water

so total number of water molecules

now we know that each water molecule will have 10 number of proton in it

so total number of protons in all the molecules is given as

now we know that total charge is given as

so we will have

so above is the charge due to all water molecules
