Can someone explain to me when to use bars versus when to use molarity during partial pressure problems? Thank you!!

I'm not sure there is a specific case when you need to use one or the other, I think it depends more on what the problems gives you.

bars are a unit of pressure just like atm or TORR

You will have to choose between bars vs molarity depending on the information given to you in the problem. If it is in bars then you use bars and vice versa.

Also, if the question asks for Kc you know you need to use concentration

bars I believe is a unit of pressure, like atm, so if given this, you would be finding Kp, versus when given molarity, that is the concentration of a molecule, and you would find Kc.
