# The Gas Equation

If Boyle’s and Charle’s law are combined, then

PV = RT (R = gas constant)

Or PV = nRT

Or

Gas equation PV = RT is for one mole of gas. For n moles of gas this equation is nRT, and is known as Ideal Gas Equation. (n = m/M, m =mass of the gas and M =molar mass of the gas).

**Nature of R:**

From gas equation:

Thus, R represents work done per degree per mole and is expressed in (in SI units).

**Value of R:**

The value of R may be calculated by substituting the values of P, V and T in gas equation.

In SI units, p = , Hence
