Question

how many electrons in 18 ml of water

Answer 1

Answer

AnswerMoles of water = mass/molar mass = 18/18 = 1.

AnswerMoles of water = mass/molar mass = 18/18 = 1.1 mole of water contains = NAmolecules.

AnswerMoles of water = mass/molar mass = 18/18 = 1.1 mole of water contains = NAmolecules.total electrons in water = 2(H) + 8(O) =10.

AnswerMoles of water = mass/molar mass = 18/18 = 1.1 mole of water contains = NAmolecules.total electrons in water = 2(H) + 8(O) =10.1 molecule of water contains = 10electrons.

Answer 2

So 18 ml of water contains 18 gm of water implies 1 mole of water. By Avogadro no. 1 mole of water contains 6.023 x 10^(23) molecules of water. But each molecule of water contains 10 electrons.
