Daniel, as you know, there are quite a few ways to express concentration other than moles per litre. For example:

*mass per volume (mg/m³, kg/m³, pounds per gallon or lb/gal)
*parts per million by volume (ppmv) and parts per million by weight (ppmw)
*molality of solutions, which is moles per mass (mole/kg)
*mole fraction (moles of component x per total moles)
*percent by volume (%v) and percent by weight (%w)
Would it not be helpful to mention at least a few of the other ways of expressing concentration? Regards, [[User:Milton Beychok|Milton Beychok]] 20:06, 29 January 2009 (UTC)
 
:I stick to SI units as far as possible but sure, go ahead. I do not have particular plans for this one, just needed it for [[Concentration (disambiguation)]]. --[[User:Daniel Mietchen|Daniel Mietchen]] 03:38, 1 February 2009 (UTC)
