Final answer:

The ideal gas law equation is PV = nRT, relating pressure, volume, number of moles, the gas constant, and temperature of an ideal gas. It combines individual gas laws and is most accurate at low pressures and high temperatures. An example shows how to calculate the volume of one mole of gas at standard temperature and pressure.


Explanation:

Ideal Gas Law Equation


The ideal gas law is a fundamental equation in chemistry that describes the behavior of an ideal gas. The equation is represented as:


PV = nRT



  • P = pressure of the gas (usually in atmospheres or pascals)

  • V = volume of the gas (usually in liters)

  • n = number of moles of gas

  • R = ideal gas constant (0.0821 L·atm/(K·mol) or 8.314 J/(K·mol))

  • T = temperature of the gas in Kelvin


This equation combines several individual gas laws (Boyle's Law, Charles's Law, and Avogadro's Law) into one comprehensive formula. It ideally applies under conditions of low pressure and high temperature, where gas particles behave independently of each other, thus approximating an "ideal" situation.


For example, if you have 1 mole of an ideal gas at a temperature of 273 K and at a pressure of 1 atm, you can use the ideal gas law to find its volume:


Using PV = nRT:


1 atm × V = 1 mol × 0.0821 L·atm/(K·mol) × 273 K


This simplifies to find V, which would equal approximately 22.4 liters. This demonstrates the relationship between pressure, volume, temperature, and amount of gas.
