Can someone explain to me how P=(Conc)RT becomes Conc=P/RT? And for clarification P stand for partial pressure right?

[Tarika Gujral 1K]

Concentration is n (mol) / V (L)

Given the ideal gas law: PV = nRT
We write P = (n/V)RT
Thus P = (Conc)RT

Then to determine concentration, we divide P by RT
And get P/RT = Conc

[ThomasLai1D]

By dividing P=(conc)RT by RT, the resulting equation would be P/RT=conc. I do not think P is necessarily restricted to partial pressures, just that it represents pressure in the formula.

[Cynthia Aragon 1B]

For a gas we use its partial pressure (P).

To convert between concentration and pressure you use the ideal gas law: PV= nRT

To ultimately get concentration, first divide by "V" on both sides of the equation to get P=(n/V) RT

n/V stands for mole/V or mol/L

Then P= conc (RT)

To get concentration by itself divide by (RT) on both sides of the equation to get P/RT = concentration

[Brianna Brockman 1F]

P=(conc)RT becomes Conc=P/RT like this:

Becasue you want to get Conc alone, you divide both sides by RT. This makes RT cancel out on the side of concentration.

now you have Conc=P/RT

A tip for converting this is you can actually set each of those to different variables that you assign on your own so you can see what's going on more easily. Then when you're done convert the variables back. Try doing this once so you can see the process clearly then you should be good!
