Discussion Overview

The discussion revolves around the units of the equation C = p/RT, where pressure (p) is given in Pascals (Pa). Participants are exploring how to convert these units into concentration expressed in mol/L.

Discussion Character

  • Technical explanation
  • Mathematical reasoning

Main Points Raised

  • One participant questions the units for C in the equation, suggesting it could be Pa J-1 mol.
  • Another participant states that pressure is defined as force applied to a surface, prompting a discussion about the units of force and surface area.
  • A subsequent reply confirms that the unit of surface is m2 and the unit of force is Newtons (N).
  • One participant suggests to "just follow from there," implying a continuation of the unit conversion process without providing specific steps.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the units for concentration or the conversion process, and multiple viewpoints regarding the definitions of pressure and its components are present.

Contextual Notes

The discussion lacks clarity on the assumptions made regarding the relationships between pressure, force, and concentration, as well as the specific steps needed for unit conversion.

Homework Statement
concentration units conversion with Pascal
Relevant Equations
C= p/RT
What are the units for C= p/RT
where p is in Pa

Would it be Pa J^-1 mol ?
and if so, how could I get the concentration in mol/L

Pressure is the force applied to the surface. What is the unit of force? What is the unit of surface?

surface is m^2
Force is N
 
Now just follow from there.
