18/18 x Avagadros number = 6.023 x 1023 molecules of water making the assumption that 1ml of water has 1 g mass. There are 8 electrons in oxygen and 1 from each hydrogen so a water molecule has 10 electrons so 6.023 x 1023 x 10 = 6.023 x 1024 electrons
***********
because 18ml of H2O = 1 mole of H2O
so. 18ml contains 6.023X1023 atoms and water has 10 electrons
so, 10 e x 6.023 x 1023 = 6.023 x 1024
An illustrative way to solve this problem.
Density water:
1 gram/ml = X grams/1 ml
= 18 grams water
================now, find amount atoms and from experience one sees that this will be Avogadro's number of atoms. 6.022 X 1023 atoms.
total atoms water * molar ratio to get atoms hydrogen. Two hydrogen atoms in compound.
2 * 6.022 X 1023 = 1.204 X 1024 atoms hydrogen, which means
1.204 X 1024 electrons hydrogen
=======================================================
Your question is irrelevant. I think that you were trying to find the number of molecules present in half a mole of water. 1 mole of water contains 6.023 * 1023 number of molecules. Hence half mole contains half of that number of molecules which is 3.0115*1023.
There is no simple answer to your question, as your question is too broad and undefined. For simple atoms, the number of valence electrons is the number of electrons in unfilled electron shells, which are then available for bonding to another atom. Oxygen with 8 total electrons has 6 paired electrons in filled electron orbitals, and 2 valence electrons in unfilled orbitals. That is why it forms bonds with 2 hydrogen molecules to form water (H2O) The number of valence electrons can change when you add or remove electrons from an atom, or in more complex atoms where filled orbitals to unfilled orbitals have the same energy and electrons can move from one to another depending on the number of other atoms it is binding with.
They are obtained from water. Photolysis of water release Electrons
You use the formula concentration x volume to find out the number of moles
If the water is impure, you could remove the impurities. If the water is pure, it's impossible to decrease the number of molecules without changing the number of water molecules, which would be the only kind of molecules present in that case.
The cobalt chloride changes colour in the presence of water because of the different amount of protons and electrons that are present.
Water molecules are composed of two atoms of hydrogen and one atom of oxygen. The hydrogen atoms each bring an electron to the reaction, and the oxygen atom brings eight. The resulting molecule has two plus eight electrons, or ten electrons in it.
There are four electrons, which is two pair.
hydrogen
stupid question.. if you found the amount of atoms in it, THEN I would be able to help you.
For a ballpark number you can multiply LxWxDx7.48
well because of the high number of electrons/valence electrons it would make a micture known as H2oGd2.
The number of neutrons will vary depending on the isotopes of hydrogen and oxygen in the molecule. The number of protons and electrons will be 10 each in every molecule.
It has the same number of electrons as it does protons, so it has a neutral charge.
