What does the constant 'n' represent in the equation of state for an ideal gas PV=nRT?
Correct answer: B. Number of moles of the gas
- A. Number of atoms in the gas
- B. Number of moles of the gas
- C. Number of nucleons
- D. Number of molecules of gas
Explanation
In the equation of state of an ideal gas PV=nRT; P is the absolute pressure of the gas in Pascals, V is the volume occupied by the gas in dm3, n is the number of moles of the gas, R is the molar gas constant (also known as the gas constant, the universal gas constant, or ideal gas constant) and T is the thermodynamic/absolute temperature in Kelvin.

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.
