Since, hydrogen atom consist of one proton and an oxygen atom consist of eight protons.
Now, density of water is 1 g/ml
Given volume = [tex]263 cm^{3}[/tex] = 263 mL
So, weight of water = 263 g
Number of moles of water = [tex]\frac{Given mass in g}{molar mass}[/tex]
= [tex]\frac{263 g}{18 g/mol}[/tex]
= 14.61 g/mol
Number of protons = [tex]14.61 g/mol\times 10\times 6.023 \times 10^{23}[/tex]
= [tex]87.99603 \times 10^{24}[/tex]
As, charge on one proton = [tex]1.6\times 10^{-19} C[/tex]
Thus, total charge = [tex]1.6\times 10^{-19} C\times 87.99603 \times 10^{24}[/tex]
= [tex]140.793 \times 10^{5} C[/tex]
= [tex]1.40 \times 10^{7} C[/tex]
Thus, [tex]1.40 \times 10^{7} C[/tex] is the total number of coulombs of positive charge.
