Abstract

The use of spreadsheets for chemistry purposes is hindered by their inability to handle the atomic symbols and molecular formulas, the basis of the chemists' language. In this paper, a Microsoft Excel 4.0 add-in function is presented, which consists of a parser to interpret molecular formulas and a database containing three values for the atomic masses for every element: the mass number of the most abundant isotope, the mass of the most abundant isotope, and the atomic weight.
