information about the yield percentage of methamphetamine from ephedrine and pseudoephedrine

A mole represents a fixed number just like a dozen or a kilo, but a mole is a huge number used to measure the mass or 
weight of a fixed number of atoms or molecules. One mole is 6.02 x 10 to the 23rd power, or 602 with twenty one more 
zeros after it. One mole is a 24 digit number. One pseudoephedrine molecule has 10 carbon, 15 hydrogen, 1 nitrogen 
and 1 oxygen atoms in it. (C10,H15,N1,O1) One mole of pseudoephedrine has 10 moles of carbon (120g),15 moles of 
hydrogen (15g), 1 mole of nitrogen (14g), and 1 mole of Oxygen (16g) which added together equal 165 grams. One 
molecule of methamphetamine is C10,H15,N1. One mole of methamphetamine is identical to one mole of pseudoephedrine 
minus the 1 mole of oxygen (16g), so one mole of meth is 149 grams. 149 is 90% of 165 grams.
