a mole of methane
a mole -- i can't do super scripts-- but its a measurement-- 10 to power of 10? a way of measuring the mass (it is mass and not volume, right?) of atoms in? (in ? a given volume?)

Ok, so i forget most of the little chemistry i learned-- but why a mole?

meanwhile, i passed one of NY's Mt gargbage's (the are two "closed" ones-- in the Bronx, and in Brooklyn) and the last remaining one is "Fresh Kills" -- and the smell of it is enough to kill you.. needless to say, that was the one i had to drive past!
