1 mole has 6,022 141 29(27)×1023 atoms.
An atom is a component of matter; mole is a unit for the amount of substance in SI. Of course a mole of atoms is bigger than a single atom.
mole
One atom of sodium weighs more than one atom of oxygen. Thus, one mole of sodium weighs more than one mole of oxygen.
If the Atomic Mass of an atom is x, then the mass of 1 mole of the atoms is x gram.
mole
The weighted atomic mass of calcium is 40.1 g/mole and helium is 4.0 g/mole
32 grams, you can find the mass of one mole of any element by looking at its atomic mass eg chlorine has Atomic mass of 35.5 so the mass of one mole of chlorine is 35.5 grams.
The hydrogen molecule is diatomic, H2.
to determine the mole of the atom
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
For the same reason that one dozen pencils has a smaller mass than one dozen bricks. Each atom of carbon weighs less than each atom of sulfur, and a mole of each has the same number of atoms, so a mole S will weigh more than a mole C.
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.
