• Molecular weight is the mass of a molecule of a substance. It can also be called molecular mass. The units for molecular weight are atomic mass units (amu). Molar mass is the mass of one mole of a substance.

Answer 2

A molecule is the smallest particle in an element or compound that still possesses the traits of that molecule or compound. For example, CO2 or carbon dioxide is a compound. The smallest particle of carbon dioxide is a single molecule of CO2. If you tried to split it up further into the elements involved in CO2, it wouldn't be CO2 anymore.

A mole (mol) is just a number. Specifically, that number is 6.022x1023, which is also known as Avogadro's number. A mol of CO2 is thus 6.022x1023 molecules of CO2. A mol, however, doesn't have to refer to molecules. As stated previously, it is just a number. That means if you see a mol of flamingos (the animal) there are 6.022x1023 flamingos. It doesn't matter what you are measuring.
