Chemists need to distinguish between these two types of atomic mass to guide their work - an incorrect value for atomic mass can, for instance, lead to an incorrect calculation of an experiment's yield. 8. Use the mass spectrum of lead, shown below, to determine the atomic mass of lead. (Estimate the values from the graph to 3 significant figures) Calculate relative abundance of each isotope from its intensity in the mass spectrum 190.87 2.67 Pb-204 = x100 = 1.40% 190.87 46.0 Pb-206 = x100 = 24.1% 42.2 Pb-207 = x100 = 22.1% The mass number for lead is 208.

The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. The atomic weights used on this site come from NIST, the National Institute of Standards and Technology. We use the most common isotopes. This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages.
