Detailed explanation-1: -Boyle’s Law states that for a fixed mass of gas at a constant temperature, the volume of the gas is inversely proportional to the pressure of the gas. In your scenario, when mass is fixed, the number of moles will be fixed, too. So we can combine both constant terms n and R to give us: PV=kT where k is a constant.

Detailed explanation-2: -For a fixed mass of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. Or Boyle’s law is a gas law, stating that the pressure and volume of a gas have an inverse relationship. If volume increases, then pressure decreases and vice versa, when the temperature is held constant.
