Joules per moles = Joules per atom x 6.022 x 1023
mole
Number of nitrogen atoms in 1 mole nitrogen dioxide? Nitrogen dioxide has 1 N atom and 2 O atoms. One mole of nitrogen dioxide has 1 mole of N atoms
Mwt means molecular weight (the larger number on the atom on the periodic table). It is the weight per mole of atom (or compound), and thus, it's units are gram per mole
One part of one mole of anything (eg. atoms in a mole atoms) is 1 / (6*10+23) = 1.6*10-24

There is no relation.
For Ideal gases, mole fraction=volume fraction
If the Atomic Mass of an atom is x, then the mass of 1 mole of the atoms is x gram.
mole
No, an atom is much smaller than a mole. An atom is the basic unit of matter, consisting of a nucleus surrounded by electrons. A mole is a unit of measurement used in chemistry to represent a large number of atoms or molecules (approximately 6.022 x 10^23 particles).
mole
1 mole has 6,022 141 29(27)×1023 atoms.
the first inoization energy is 2372.3 kJ mol-1 there are 6.0221415 × 10^23 in a mole from avagadros number, devide the ionization energy for one mole by the number of atoms in a mole and you get the first ionization energy for one atom.
The hydrogen molecule is diatomic, H2.
to determine the mole of the atom
One atom of sodium weighs more than one atom of oxygen. Thus, one mole of sodium weighs more than one mole of oxygen.
There is no general exact relationship, because of the existence of neutrons in the nuclei of almost all elements and the lack of effect of neutrons on atomic number. An atom's gram atomic mass, however, is equal to the mass of one mole of the atoms in question.
