RE: "molar" for concentration

hi lena,



after looking at wikipedia i see what you mean that it isn't a unit per se,
it is a concentration of a solution, that is by definition a combination of
a value of 1 with an SI unit of 1 mol\L.  so it is certainly a property of
the solution but i don't see how it is a datatype.  in programming terms i
define a variable to be of a certain datatype:



int count = 5



what does it mean to say,



Molar solution = ??



cheers,

michael

Hi Michael,



I did mean datatype. I do like the MUO / SI solution, but it's strange that
they don't describe "Molar" (much more widely used) along with "mole"? Sure
enough I can "build" a Molar, as Jim indicated... but I can also "build" a
month or an acceleration from days or meters+time, and yet they provide
it... Interesting...



Thanks all,

Cheers,

Lena

hi all,

i did take a quick look at MUO and it does seem sane.


"For instance, MUO has the ability to assert units of measure on n-ary

observations, ..."

and MUO appears based on SI.
