Mole vs Molecule | Difference between mole and molecule

Q. What is the difference between a mole and a molecule?

Ans:

MOLE: A mole is a fixed number, that is 6.02x10²³ it is also known as Avogadro's Number because Sir Avogadro was the person who calculated about 6.02x10 molecules and gave it the name "Mole". So mole is also used as unit for molecules. For example if we say one mole of hydrogen that means 6.02x10 molecules of hydrogen.

Chemical Reaction

Q. What is a Chemical Reaction?

A chemical reaction occurs when two or more molecules interact with each other. They form bonds and create a new molecule.

In a chemical reaction, the molecules that interact with each other are called reactants and the molecules produced by the reaction are called products. During a chemical reaction, no new atoms are created or destroyed. A reaction could include atoms, ions, compounds or molecules of a single element. The reactants contact each other, bonds between the atoms are destroyed and they rearrange to form new bonds and as a result products are created.

Molecule

Q. What is Molecule?

A group of atoms bonded together makes a molecule. Because an atom is so small that we cannot see it but when many atoms of same element combine together that makes a compound that is visible to our eyes and we can use it in reactions.

So.. The definition of atom is:

A group of atoms of same element bonded together.
