1 The relative atomic mass, or atomic weight, of an element is the weighted average of the masses of the isotopes in the naturally occurring element relative to the mass of an atom of the carbon-12 isotope which is taken to be exactly 12.
Definition: Relative uncertainty is a measure of the uncertainty of measurement compared to the size of the measurement. Also Known As: relative error. Examples: Three weights are measured at 1.05 g, 1.00 g, and 0.95 g. The absolute error is Â± 0.05 g. The relative error is 0.05 g/1.00 g = 0.05 or 5%.
