### w

do you need Avogadro's number to find degeneracy?

I think this is because we want to find one mole's worth, which is avagodros number in terms of atoms or molecules.

You need to multiply N by Avogadro's number to calculate the degeneracy of N moles of a certain substance, but not to calculate that of N particles.

No, you don't need Avogadro's number to find degeneracy. You will only use Avogadro's number for degeneracy if you are finding the degeneracy of a mole of molecules.

### Re: w

You don't necessarily need to use Avogadro's constant to find degeneracy but if a question requires you to know the degeneracy of a mole of a substance, Avogadro's constant is needed for the value of the "number of particles" within the states.

### Re: w

You would only need to apply Avogadro's number if the question asks you to find the degeneracy of a mole of the given substance.

Only if you are looking in the context of per mole.

We do need to use Avogadro's number if we want to find the degeneracy of N moles of a certain substance. However, if you are simply calculating the degeneracy of a certain number of particles, you do not use Avogadro's number.

Well said here! Just like with the first law of thermodynamics, we need to consider context/all factores, here whether we are looking for degeneracy per mole or just amongst particles-- if you need to figure it out per mole, you'll need Avogadro's number.

You would only need Avogadro's number if you were to find the degeneracy of a specific number of moles of a molecule, much like how you would only use Avogadro's number to find the mass of only one atom of an element when given the molar mass.

Yes, if looking in terms of per mol

Yes, if you're working with moles.
