The number of moles is 0,4375.
8,75 moles of oxygen are needed.
12 right?
.003 mols .003 mols
divide by Avogadro's number to get 0.090 mole
The number of water molecules obtained is 120,44281714.10e23.
8,75 moles of oxygen are needed.

Any
1 mol of oxygen is 16.00g. Therefore 2.43g of oxygen would contain 0.152 mols of oxygen. (2.43g/16.00g)
using Avagadro's number you can go from a number of something to mols, or you can go backwards, from mols of something to particles/atoms/molecules etc.
you would get 6.4 mols of NaCl and 0.3 mols of unreacted Na
Exactly the same number of mols. 1 mol of oxigen atoms produces 1 mol of water molecules.
firstly, you cannot have 1.20105 molecules, it is physically impossible to have a non-integer number of molecules. But I will assume you mean 1.20105 mol. Simply multiply the number of mols of oxygen atoms by avagadros number so 1.20105 mol of n205 = 1.20105*5mol of oxygen atoms. 1.20105 x 5 x 6.022e-23 is your answer
The water molecule is made up of 2 atoms of Hydrogen and one atom of Oxygen. So a total of 3 atoms. For other measurements, google Avogadro, mols, etc.
Mols-Linien was created in 1964.
