A molecule, for example of water, contains 2 hydrogen atoms and 1 oxygen atom chemically bounded together and is the smallest building block of the chemical water. The molecules are then held together by intermolecular forces, in this case by strong hydrogen bonds.
A mole is a certain quantity of molecules, namely the Avagadro number of molecules NA=6.023×1023.
So for example if you take 6.023×1023water molecules then that makes up 1 mole of water.
Its mass would be the molar mass of water, meaning that 1 mole of water with that large number of particles has a mass of Mr=1+1+16=18g/mol.
By definition, 1 mole is said to be the number of particles contained in 12g of the carbon-12 isotope.

Moles and molecules are two very different things. Mole is the unit to measure the amount of a substance while a molecule is a chemical species formed by the combination of two or more atoms of same or different elements whose properties are very different from that of the combining elements.
One mole of a substance is that quantity whose mass is equal to its atomic or molecular mass in grams. One mole of any substance contains 6.022 × 1023 particles (atoms, molecules, or ions). This means that one mole atom of any element contains 6.022 ×1023 atoms. Similarly, one mole molecule of a compound contains 6.022 ×1023 molecules, and one mole ion of any substance contains 6.022 ×1023 ions. For example
1 mole of Na atoms = 23 g of Na atoms = 6.023 X 1023 atoms of Na
Similarly 1 mole of water (H2O) molecules = 18 g of water molecule = 6.023 X 1023molecules of water
Hence one mole molecule of a compound would always contain 6.022 ×1023 molecules.
