But for these units, this will be our gas constant. So the question is how does an ideal gas law help us? Well, it helps us in the following way. If we know three parameters, we can find and find them unknown. That's exactly what this formula tells us. If we know, for example, Nt and D, we can find P.
Or if we know p, d and T will find N. Or if we know p, n and T will find D and so on.
