C1 * V1 = C2 * V2 

I agree, this equation should be second nature to a chemist.
It doesnt matter what units the C's are in so long as you use the
same on both sides.  Same with volumes.

Sure, especially if you use molality.

Most users of chemistry haven't heard of molality. Those that need to have (usually :) ).
The equation above, OTOH, is very useful :) 

Never stated opposite :) It is even part of my lectures (link posted
earlier - chembuddy.com/?left=lectures and look for concentration,
then dilution and mixing). Just the remark that it always holds is a
little bit too general.

Have you ever heard about molinity? :)

Best,
