PV NRT

PV NRT, The ideal gas law (PV = nRT) is unlike the other gas laws in that it does not require an initial and a final state, ie it does not require the situation changes in order to determine a value for pressure, volume, amount of gas or temperature.

PV = nRT

When R * = 0.082 atm L / mol * K

We can determine the pressure, volume, temperature or quantity of gas (n) when others are known. For this we must use in atmospheres of pressure, volume in liters, the amount of gas in moles and the temperature in Kelvin.
