✔ But each molecule of water contains 10 electrons. Thus 6.023 x 10^(23) molecules of water will contain 10 x 6.023 x 10^(23) electrons= 6.023 x 10^(24) electrons.

✔ 18 ml of water is equal to 18 g of H20.


i hope help u jii

Hey mate ^_^

Answer:

Here we will use the the concept of density of water = 1g/cc

D=M/V

1 g/ml = M/18 ml

M= 18 g

Moles of water = mass/molar mass = 18/18 = 1

1 mole of water contains = NA molecules

Total electrons in water = 2(H) + 8(O) = 10

1 molecule of water contains = 10 electrons

1 mole water contains = 10 * NA electrons

NA = Avogadro’s number
