The mass of a single lead atom is 207.2 AMUs (atomic mass units) which when converted to grams weighs 3.440e-22 grams. Huzzah. The mass of a single lead atom is 207.2 AMUs (atomic mass units) which when converted to grams weighs 3.440e-22 grams. Huzzah.
The atomic mass is useful in chemistry when it is paired with the mole concept: the atomic mass of an element, measured in amu, is the same as the mass in grams of one mole of an element. Thus, since the atomic mass of iron is 55.847 amu, one mole of iron atoms would weigh 55.847 grams. The same concept can be extended to ionic compounds and molecules. One formula unit of sodium chloride (NaCl) would weigh 58.44 amu (22.98977 amu for Na + 35.453 amu for Cl), so a mole of sodium chloride would weigh 58.44 grams.
