What constants do we need to know? Are we responsible for things like Uo and permittivity of free space, etc?

The only one I've seen from AAMC material is Avogadro's number. For almost anything else, they either give you the constant or express the answer in terms of the constant.

Definitely not permittivity. The ones I can think of off the top of my head are the speed of light in a vacuum, Avogadro's number, and Faraday's constant. They'll provide most of them.

I could be wrong, but I don't even think Faraday's is required for memory.

I haven't seen Avogadro's either.

I will probably go through an memorize those anyway though just because they aren't really hard.

How about R in equations like PV = nRT and Vroot mean square = square root of 3RT/m ?

R value keeps changing, depending on what kind of equations you are using and this keeps messing me up.

I'm almost certain I've seen Avogadro's on one of the practice AAMCs. Light of speed was given and the question related to Faraday's did not really need the value.

Worst case - just spend 10 minutes and memorize them.
