Determine atomic weight
WebAvogadro's number is the ratio of the mass of 12 grams of carbon-12 to the mass of 1 atom of carbon-12 measured in grams. Or, a little easier to understand, Avogadro's number is the ratio of 1 gram to 1 atomic mass unit but with the atomic mass unit expressed in grams. Thus, Avogadro's number has been measured to be 6.022141×10²³.
