What is the difference between mole and molecule.
https://www.dictionary.com/
They are completely different things; I'm not sure why they would be compared to each other. A mole is an amount of a substance, a molecule is a group of atoms.
A molecule is formed when two or more atoms are joined. For example two oxygen atoms join to form the oxygen molecule. Same with two H to form H2 and Cl to make Cl2. Those are diatomic molecules (two of them). Another example of a molecule is salt, NaCl, or sugar, C12H22O11.
A mole is an AMOUNT in grams of something. A mole of H2, for example is 2 grams. The atomic mass of H is 1 so two of them makes 2 grams. O2 is 16*2 = 32 grams. A mole of C12H22O11 is 342 grams. I wish we had different names for mole and molecule because the beginning student gets confused over them all the time.
a mole is a number of things ... like a dozen ... only MUCH bigger
it is a very large number (Avogadro's number, 6.02E23)) , so it is not used much for anything other than atoms or molecules
it is the ratio between atomic mass units (amu) and grams
... a mole of a substance has the same mass in grams , as the mass of an atom (or molecule) of the substance in amu
The difference between a mole and a molecule lies in their definitions and what they represent in the world of chemistry.
A molecule is the smallest unit of a chemical compound that maintains its chemical properties. It consists of two or more atoms that are chemically bonded together. For example, water (H2O) is a molecule composed of two hydrogen atoms bonded to one oxygen atom.
On the other hand, a mole is a unit of measurement in chemistry. It represents an amount of substance and is used to count and measure the quantity of atoms, molecules, or other particles. One mole is defined as the amount of substance that contains as many entities, such as atoms or molecules, as there are atoms in exactly 12 grams of carbon-12. This value is approximately equal to 6.022 x 10^23 entities and is known as Avogadro's number.
To summarize, a molecule is a structure composed of two or more atoms bonded together, whereas a mole is a unit of measurement representing a specific quantity of atoms, molecules, or particles.
