The atomic masses shown in the Cannabis Periodic Table of Molecules  chart were determined by public references or the chemical formula. In the case of the latter, each element’s molecular mass was identified and totaled. To provide an example, for water (H20), Acannability’s team identified two hydrogen elements with mass ~1 each and one oxygen element with mass ~16, totaling 18 for the molecule. After identifying or calculating the atomic masses of all the molecules, the table was constructed to reflect an objective structure, similar to the Periodic Table.
