About Ideal Gas Law
The ideal gas law, also called the general gas equation, is the equation of state of a hypothetical ideal gas. It is a good approximation of the behavior of many gases under many conditions.
It is stated as PV = nRT, where P is pressure, V is volume, n is the amount of substance (moles), R is the ideal gas constant, and T is the absolute temperature.
Ideal Gas Formula
PV = nRT
P = Pressure
V = Volume
n = Amount (moles)
T = Temperature
Using Ideal Gas Constant R = 0.08206 L⋅atm/(mol⋅K)
