Ideal Gas Law Calculator: The Online tool on Ideal Gas Law makes it simple to determine the parameters of an ideal gas when pressure, temperature, and volume change. In this post, you can discover solutions to all of your queries about ideal gases. Continue reading to learn about the definition of an ideal gas, its equation, the ideal gas constant, and how to get the unknown parameter in an ideal gas equation.

Ideal Gas Law Formula

The formula pV = nRT is the emperical form of the Ideal Gas Law Equation.

  • p denotes the gas pressure in units of pa.
  • The volume of the gas is V and it is measured in m3.
  • The number of moles is denoted by the symbol n.
  • The Ideal Gas Constant is R.
  • T stands for the absolute temperature of a gas, which is expressed in Kelvins.

The Ideal Gas Law Constant

We can get the ideal gas law equation by combining Robert Boyle, Gay-Lussac, and Amedeo Avogadro's observations. In the next modules, we will first master the specific expressions of charle's law, boyle's law, avagadro's law, and so on.

According to Boyle's Law, V∝1/P

According to Charle's Law, V∝T

According to Avagadro's Law, V∝n

We derive the equation V∝nT/P by combining all of these formulas. Volume is directly proportional to moles and temperature, and inversely proportional to pressure, as seen in the preceding equation.

The result of rewriting the equation is V=RnT/P. To eliminate the fraction, multiply the equation we obtained with P, and we get PV=nRT.

As a result, The above equation is referred to as the ideal gas equation.

Ideal Gas Law Examples

Question 1: Find temperature of a gas if the pressure is 12.0 pascal under the volume is 20mm3 with the amount of substance is 4mol.

Solution:

Consider the problem, we have

Pressure = 12.0 Pa

Convert Volume 20 mm3 into m3

Volume = 2x10-08 m3

By using the formula pV = nRT is the emperical form of the Ideal Gas Law Equation.

Convert 7.216742843396681x10-09 Kelvin into celsius

Temperature = -273.14999999278325 celsius
