A mole, in terms of chemistry usually, represents a number. That number is about 6.022 x 10^23. So when you have a mole of something, you have 6.022 x 10^23 of something. Moles are used in chemisty because the mass of a mole of any molecule in grams is the same as the Atomic Mass of the molecule in amu's.

Is an atom bigger than a mole?
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.
What weighs more one mole of oxygen or one mole of sodium?
One atom of sodium weighs more than one atom of oxygen. Thus, one mole of sodium weighs more than one mole of oxygen.
Why does one mole of carbon atoms have a smaller mass than one mole of sulfur atoms?
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.
Ionization energy of a helium atom is helium gas per mole?
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.
Mass of 1 mol of oxygen atoms?
mass of one mole of oxygen atom is 16 grams. atomic weight of any atom is equal to mass of 1 mol of that atom...

What is 1 gram of atom?
mole
What weighs more one mole of oxygen or one mole of sodium?
One atom of sodium weighs more than one atom of oxygen. Thus, one mole of sodium weighs more than one mole of oxygen.
What is the relationship between an Atoms mass and one mole of that atom?
If the Atomic Mass of an atom is x, then the mass of 1 mole of the atoms is x gram.
What unit is used to measure the mass of an atom?
mole
What is the mass of calcium atom compared with the mass of helium atom?
The weighted atomic mass of calcium is 40.1 g/mole and helium is 4.0 g/mole
How do you find mole in atom?
1 mole has 6,022 141 29(27)×1023 atoms.
Why one mole of hydrogen and one mole of H-atom have different masses?
The hydrogen molecule is diatomic, H2.
Why are coefficients used in chemical equations?
to determine the mole of the atom
What is Mwt?
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
Why does one mole of carbon atoms have a smaller mass than one mole of sulfur atoms?
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.
