Resumen de An Excel 4.0 Add-In Function to Calculate Molecular Masses
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.
