Nit picking my nitpic? Hmmm, is anyone keeping score? :-) You are
correct of course but maybe we can take a closer look.
Lets-see-here-now, we have density in moles/L^3. Is that a nuclear
density?

The way I see it, if the units of the denominator is length cubed, it's a
density of some sort! That's all a man can ask for - and expect - some
days! ;-)

Whatever it is it must be a Chem E thing... I've seen flow
rates in moles/hour, but this is new. Ya never can trust those Chem E
types anyways.

Add physics grads to the types you can't trust. ;-) You do realize that
physicists consider 1, pi, and 4.9 to all equal 1, while 11, 33, and 49 are
all equal to 10? They love to round to the nearest power of 10, so they can
reduce all multiplcations and divisions to additions and subtractions of
powers of ten. We never learned math beyond adding and subtracting. :-)

I figured you chose to skip a few steps to get to the answer sooner
and avoid losing the audience. It's a tough call on the minor
technical details. I probably err in the other direction too often. I
figured this group has some folks that wouldn't mind seeing an
expanded explanation in a separate post.

I was sure people's eyes had glazed over before they finished reading.
What's a few lazy mistakes among friends, eh?

While I'd love to expand on my explanation, as I write this I believe a new
episode of Mythbusters comes on in ~15 minutes and I know I wont be able to
compose an accurate post in that amount of time. And my short attention
span means I'll never get round to it later. (Did I mention I did better in
QM than statistical and thermo physics and that I'm really rusty in both
now? Or as Scotty once said: "I canna change the laws of physics Captain! I
need 30 minutes!")
