Chem Standard

I am a member of the transition metals. I will teach you standard 3C: Students know one mole equals 6.02x10²³particles (atoms or molecules). Simply put, the mole represents a number. Just as the term dozen refers to the number twelve, the mole represents the number 6.02 x 10²³.Now that's a big number!The mole is used when were talking about numbers and molecules. Atoms and molecules are very tiny things. A drop of water the size of the period at the end of this sentence would contain 10 trillion water molecules. Instead of talking about trillions and quadrillions of molecules (and more), it's much simpler to use the mole.The number of objects in one mole, that is, 6.02 x 10²³, is commonly referred to as Avogadro's number. Amadeo Avogadro a Italian scientist created the term and concept of the mole.

Defining moles?

• 1 mole of molecules has a mass equal to the molecular weight in grams.
• 1 mole of atoms has a mass equal to the atomic weight in grams.
