A program for calculating elemental composition from a chemical formula by Massimiliano Arca
A scientific program by Massimiliano Arca - Cagliari (Italy)
An older version Elemental, programmed in Pascalated Boriel Basic, was submitted to the Pascalated Basic Contest 2024.
Elemental Analysis (EA) is a common microanalysis used to investigate the percentage (%) composition of an analyte in terms of its main elements, typically carbon (C), hydrogen (H), nitrogen (N), and sulfur (S). For example, the formula of glucose is C6H12O6, corresponding C% = 40.0%, H% = 6.7%. This means that in 100 g of sugar, 40 g are due to the carbon content, 6.7 g to the hydrogen content and 53.3 g (the difference to 100 g) to the oxygen content.
It is possible to determine the EA of a chemical compound experimentally: in order to investigate its chemical nature, the experimental values can be compared with those calculated from the formula. From the formula, in turn, it is possible to calculate the molecular mass (MM, i.e. the mass of one mole of the compound).
