Perhaps > weighs your teeth?? :-) "Molar" as in the adjective describing "mole" as in "quantity of matter" as in "some gigantic number of identical atoms (or maybe it's molecules)". It's a very useful measure of "some quantity of stuff". IIRC the gigantic number is Avogadro's number, on the order of 10^124. So one mole of hydrogen would be the amount of hydrogen containing that number of hydrogen atoms (or maybe it's molecules. Whatever.) -- alan dot mckinnon at gmail dot com
