Average atomic mass of carbon = (percent abundance 12 C)(atomic mass 12 C) + (percent abundance 13 C)(atomic mass 13 C) Average atomic mass of carbon = (0.9890)(12.000 amu) + (0.0110)(12.00335 amu) = 12.01 amu. Remember to convert the percentages into fractions before doing the calculation or you'll end up with some outrageously incorrect Das Atomic Mass Data Center setzt eine Tradition fort, die der Chemiker und Physiker Francis William Aston begründet hat.

This module shows how the mole, known as Avogadro’s number, is key to calculating quantities of atoms and molecules. It describes 19th-century developments that led to the concept of the mole, Topics include atomic weight, molecular weight, and molar mass. One atomic mass unit is equal to 1.66 x 10-24 grams. One unified atomic mass unit is approximately the mass of one nucleon (either a single proton or neutron) and is numerically equivalent to 1 g/mol.
