What is Avogadro's Number?
Summary
What is Avogadro's Number?
Answer
6.02214179 x 10^23. This is the number of atoms determined to be in 12 grams of carbon-12, which was chosen arbitrarily as the reference unit for the Mole. The number is a scaling factor between macroscopic and microscopic observations of nature.

It is the number of atoms or molecules that are contained in the amount of a substance given by one Mole. It is the proportionality factor that relates the molar mass of a material to its mass.

The capital M associated with a solution's concentration indicates the number of Moles per Liter of water of that item.
