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
No, a water molecule contains the same number of protons and electrons. In a water molecule (H2O), there are 10 protons (2 from each hydrogen and 8 from oxygen) and 10 electrons (2 from each hydrogen and 8 from oxygen).
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.
To calculate the moles of water, you can use the formula: moles = mass of water (in grams) / molar mass of water (about 18.015 g/mol). Simply divide the mass of water by its molar mass to find the number of moles.
To find water by mass in a compound, you can calculate the difference in mass before and after heating the compound to drive off the water. The lost mass represents the mass of water present in the compound. You can then calculate the percentage of water in the compound by dividing the mass of water by the total mass of the compound and multiplying by 100.
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.
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.
In one liter of water, there are approximately 3.34 x 10^25 molecules of water. Each water molecule contains 10 electrons (2 from each hydrogen atom and 8 from the oxygen atom), so there are approximately 3.34 x 10^26 electrons present in one liter of water.
hydrogen
Hydroxide and water are isoelectronic with fluoride as they have the same number of electrons.
For a ballpark number you can multiply LxWxDx7.48
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.
