What does the constant N represent in the equation of state for an ideal gas PV=NkT?
Correct answer: A. Number of molecules and atoms (particle) of gas
- A. Number of molecules and atoms (particle) of gas
- B. Number of moles of the gas
- C. Number of nucleons
- D. Number of protons
Explanation
The ideal gas law states that PV = NkT, where P is the absolute pressure of a gas, V is the volume it occupies, N is the number of atoms and molecules in the gas, and T is its absolute temperature.

About Ideal Gas Equation
The ideal gas equation, PV = nRT, relates pressure, volume, amount and absolute temperature when gas particles are assumed to have negligible volume and no intermolecular forces. Applications include finding molar mass, density or an unknown gas variable, with careful use of Kelvin temperature and consistent units, and comparison with real-gas behaviour.
