C/H/N/O (Carbon, Hydrogen, Nitrogen and Oxygen) Elemental analysis calculator software free download for chemistry and CHNO is a program that calculates ratios of the atoms C, H, N and O present in compounds from which
the elemental analysis (mass%) are known.
C_H_N_O accepts input values for mass % of the elements C (Carbon), H (Hydrogen), N (Nitrogen) and O (Oxygen). If a value for O is not explicitily given in a compound that contains oxygen it will be calculated by the formula: O%= 100%-C%-H%-N%.
