PV=nRT

[Stanley Munoz 3F]

When calculating pressure is P=[concentration]RT the same as P=nRT/V?

I believe they are the same! (n/V)*RT is equivalent to nRT/V. (n/V) is how you calculate concentration (moles of substance divided by volume), so the other way you wrote this equation is useful when a problem has concentration as a given value. Hope this helps!

Hello, I believe that is the same thing! The formula for concentration is moles over volume or essentially n/V. So basically it is PV=nRT but with P isolating and dividing V on both sides.

[Sarah Yang 1B]

Yes, these two equations are the same! n/V or moles divided by volume is concentration.

[Alysha Dijamco 3E]

Yes, they are the same! In order to calculate concentration, you can divide the moles of a substance by the volume, which can be represented at n/V. When looking at the equation P = nRT/V, you can see that there is a n/V, representing concentration. Thus, when given the concentration, you can substitute it in the equation so that it can be P = [concentration] x RT. This is helpful when you want to convert between partial pressure and concentration as you can also find concentration by dividing P by RT (concentration = P/RT).

Yes! n/V is moles/volume, which is how you calculate concentration. Therefore, [concentration]*RT = P is the same as nRT/V = P.

[VictoriaPietrusiew2H]

Yes, PV=nRT is the same as P=[conc]RT, since the concentration is equal to moles over liters (n/V), thus since P = (n/V)RT and concentration = (n/v), these equations are equal.

[VictoriaPietrusiew2H]

Yes, PV=nRT is the same as P=[conc]RT, since the concentration is equal to moles over liters (n/V), thus since P = (n/V)RT and concentration = (n/v), these equations are equal.

[AbenaaMensahBonsu2F]

Yes, the equations are essentially the same one is just derived from the other.

[Kimberly_Wu_3H]

Yes, both are the same as n/V or moles divided by volume is concentration.

[Emily Ng 3D]

Yes, P=[concentration]RT is the same as P=nRT/V as n/V in the second equation is equal to the concentration of the first.

[Ciabel Querol 3E]

Yes, they are equivalent equations! If you rearrange P=nRT/V, it becomes P=n/V*RT. Concentration is the number of moles of substance in solution divided by amount of liters of solution, aka n (number of moles) / V (volume). P=n/V*RT thus becomes P=[concentration]*RT. Hope this helps!

[Camila Garcia 1F]

Yes it would be considered the same. Since the units for concentration is mol/liters, the p=nrt/v will simplify to n/v which is molarity.
