accurate mass

The accurate mass (or exact  mass) of an ion of specified isotopic composition is calculated  by summation of the exact  masses of the constituent  atoms. Conversely, the empirical formula of an ion can be deduced from the measured accurate mass of the ion if the ion mass is low enough to limit the number of formulaic possibilities and if the exact mass value is known accurately enough.
