MolecularFormula Analyze

Analyze a molecular formula to calculate molar mass, degrees of unsaturation (DoU), and elemental composition (mass percentages). OR determine empirical/molecular formula from combustion analysis data (masses of CO2, H2O produced from burning a sample). Supports elements: C, H, N, O, S, P, F, Cl, Br, I. Use for: formula analysis, combustion analysis problems, elemental composition, molecular weight calculation.
