Ideal Gas Equation

Introduction

The three historically important gas laws derived relationships between two physical properties of a gas, while keeping other properties constant:




It is the most basic equation of state, assuming that the particles in the gas behave in such a way that they do not interact with each other at all, and approximate point masses. This makes the math very simple as the extensive state of an ideal gas is only a function of temperature, pressure, and volume.

P V = n R T

Application

There are three common applications of Ideal Gas Equation.

• Calculation of Molar Volume 
• Calculation of Density 
• Calculation of Molar Mass (weight of one mole) 

Properties of the gaseous state predicted by the ideal gas law are within 5% for gases under ordinary conditions.
