New Lessons in Chemistry from the AZNT Web Site To fully appreciate today's lesson, you may want to look at or print out the AZNT Touch of Nature web page: amazon-treasures.com. On the second half of the page there is a table whose columns include the chemical formulas, molecular weights and "degree of dulciness" of Touch of Nature A, B, C and D respectively. The contents of this table are quite fuzzy, particularly the chemical formulas, so I would appreciate some of you checking that I've read them correctly. My reading of the chemical formulas and the corresponding molecular weights are: ToN A: C44-H70-O23, Mol. Weight = 804.9 ToN B: C39-H60-O18. Mol. Weight = 967.0 ToN C: C44-H70-O73, Mol. Weight = 967.0 ToN D: C44-H80-O77, Mol. Weight = 951.0 Computation of molecular weights from their chemical formulas isn't rocket science - it only involves simple arithmetic. Here's a web page that explains the process and gives a formula that can be used to calculate the molecular weights of each of the four ToN molecules: chem.arizona.edu. As you can see, one simply uses the atomic weights of each type of atom times the number of that type of atom to calculate the total contribution of that type of atom to the molecular weight. One then sums the contributions of each of the different types of atoms. For example, hydrogen has an atomic weight of approximately 1.008 and oxygen has an atomic weight of approximately 15.99. Thus H2O (2 hydrogen atoms plus one oxygen atom) will have an atomic weight of (2*1.008) + 15.99 = 18.006. To check the computation yourself you will also need the atomic weight of carbon. Per the above web page it is 12.01. What are the molecular weights of each of the four ToN molecules? By my calculations, they are: ToN A: 966.77 (AZNT's answer: 804.9) ToN B: 816.69 (AZNT: 967.0) ToN C: 1766.27 (AZNT: 967.0) ToN D: 1840.31 (AZNT: 951.0) Assuming I haven't read the data wrong, it appears that Touch of Nature really is special. It certainly seems to defy the rules for computing molecular weights. I hope that Dr. Loricchio played no role in preparing or reviewing the content of this web page. It's not exactly the sort of thing one would expect from an internationally known biochemist who is a graduate and former professor in chemistry at the Sorbonne (#reply-5590114 ). Assuming I'm correct, undoubtedly he will wish to have the page corrected. Could you ask the Webkmaster to make the structure diagrams at the bottom of the page readable at the same time?
