Equation of Ideal Gas Law
These two laws apply to low-density gases and can be grouped into a single relationship. It’s worth noting that,
PV = Constant…(1)
V/T = Constant…(2)
From eq(1) and (2)
PV/T = constant
It can be stated in a more general form that applies to any quantity of any low-density gas, not simply a specific quantity of that gas. This relationship describes the ideal gas law and knows as the ideal gas equation.
It can be expressed as,
PV / T = nR
PV = nRT
where,
n is the number of moles in the sample of gas
R is the universal gas constant
Note: The universal gas constant (R) has a value of 8.314 kJ/mole in the SI system.
It can also be stated in a more general form that applies to any quantity of any low-density gas, not simply a specific quantity of that gas.

Ideal Gas Law
The ideal gas law also called the general gas equation, is an equation that provides the relation among the various parameters of the gas i.e. they provide the relation among pressure(P), temperature(T), and Volume(V) of the gas. It is a combination of Charles’s law, Boyle’s Law, Avogadro’s law, and Gay-Lussac’s law. This law was first stated by the French physicist Benoit Paul Émile Clapeyron in 1834.
