Homework Answers
Moles/L is not the unit of pressure.It expressed the unit of molarity.
Psi is a unit of pressure. Pressure measured as when 1 pound force applied on square inch.
So moles/L is not unit of pressure.
Add Answer to:
all
of the following are pressure units EXCEPT
Pressure and volume are indirectly related. Question 2...
