The Ideal Gas Law is probably the most complex of all the laws mentioned on this wiki. Most of the time you are solving for 'R' or the Ideal Gas Constant. The equation is written as:

PV=nRT

If you are given that the pressure is 1 atm, the volume is 22.4, there is 1 mole, and the temperature is 273 K, what is R?

First, substitute all the given values...

(1)(22.4) = (1)r(273)

Simplify

22.4 Latm = 273R molK

Because you looking for R, you need to isolate the variable by dividing each side by 273 molK, leaving you with:

__22.4 Latm__ =  R 273 R molK

Then simplify to get your answers, keep in mind all the units (they're kinda crazy)

.082 Latm/ molK = R
