Discussion Overview

The discussion centers around the definition and application of molarity in chemistry, specifically whether it can be simply defined as "moles per liter" and the implications of using this definition in various contexts, including the concept of using empty space as a volume.

Discussion Character

  • Conceptual clarification, Debate/contested

Main Points Raised

  • Some participants affirm that molarity is simply "moles per liter."
  • One participant references a definition from WIKI, noting that molarity is a measure of the concentration of a solute in a solution or any species in a given volume, and questions whether this "given volume" can be empty space.
  • Another participant suggests that while there is no technical reason to avoid using molarity in the context of empty space, it may not be practical or widely accepted, indicating a potential disconnect between theoretical and practical applications.

Areas of Agreement / Disagreement

There is general agreement among some participants that molarity can be defined as "moles per liter," but there is disagreement regarding the practical application of this definition, particularly in relation to the concept of empty space as a volume.

Contextual Notes

The discussion highlights limitations in practical applications of molarity, particularly when considering unconventional definitions or contexts, such as using empty space as a volume.

Yes.
 


Yup.
 


WIKI states that

"In chemistry, molar concentration, also called molarity, is a measure of the concentration of a solute in a solution, or of any molecular, ionic, or atomic species in a given volume."

Can the "given volume" be empty space?
 


Generally speaking I can't see a reason why you can't use molarity this way, although you will be in troubles - because it is usually not used that way. First you will have to convince everybody around to use such units. But technically they seem to be OK, unless I am missing something.

Question is, whether you will find practical application, creating units for units sake doesn't make sense.
