1023 Na atoms ( 1mol Na/6.022 X 10^23 )(22.99g Na/1mol Na ) = 3.905 X 10^-20 grams
1 mole of sodium weights 23g 1 mole of sodium = 6.02 x 10^23 atoms = 23g 117 atoms = ? 117 x 23 / 6.02 x 10^23 (should be a very small number)
You would expect to find nitrogen and oxygen as molecules in the atmosphere, and argon as individual atoms.
A metallic bond.
The chemical formula for sodium oxide is Na2O (with the '2' written in subscript). So in one formula unit of sodium oxide, there is one sodium and two oxygen. 1 mole of sodium oxide would have 3 x 6.02 x 10^23 = 1.81 x 10^24 atoms.Sodium oxide is made of sodium and oxygen atoms. The chemical formula of it is Na2O. There are 3 atoms in 1 molecule of Na2O.
a mole of deuterium weight 2,014g
Sodium has an atomic mass of 29.990 g/mol. This means that 124 sodium atoms have a mass of 3718.76 amu, if the isotopes follow the average. To find in grams, the following must be used: 124 sodium atoms equal 2.0598 * 10-22 moles, so 124 sodium atoms have a mass of 6.177 *10-21 grams.
1 mole of sodium weights 23g 1 mole of sodium = 6.02 x 10^23 atoms = 23g 117 atoms = ? 117 x 23 / 6.02 x 10^23 (should be a very small number)
you only find 1 type of atom in an element
Nothing.4 atoms of sodium would have a 4 + charge and 5 atoms of oxygen would have a 10 - charge.So you need 2 atoms of sodium and 1 atom of oxygen to get...,Na2O=====
345 magnesium atoms weigh 1,4.10e-23 g.
Well sodium is salt so I would expect nearly everywhere
sodium
You would expect to find nitrogen and oxygen as molecules in the atmosphere, and argon as individual atoms.
A water solution of sodium chloride is neutral.
Water solution of sodium chloride is neutral.
A metallic bond.
That would depend on how much you have to weigh.
