At last confirming the pigment was delphinidin-3-O-glucoside, the molecular formula is C21H21O12.
From the molecular formula alone, we can deduce the "degrees of unsaturation" in the molecule.
Menthol is a chemical agent, menthol by the mint leaves and stems in the extract, white crystals, molecular formula C10H20O, mint, and peppermint oil to the main ingredient.
Ammonium di-iso-butyl dithiophosphate and ammonium din-butyl dithiophosphate is isobutyl isomers, they have the same molecular formula, only alkyl isomers.
"It is calculated in practice by summing the atomic weights of the atoms making up the substance's molecular formula. The molecular weight of a hydrogen molecule (chemical formula H2) is 2 (after rounding off); for many complex organic molecules (e.g., proteins, polymers) it may be in the millions."
Similarly, molecular formulas have to have subscripts after the element name, not before.
