**On exams, you will be expected
to calculate numerical answers, without being given any of these basic
numbers.**

You do not have to memorize
this exact list, as long as the numbers you did memorize allow you to do
equivalent calculations. For example, knowing that a_{B}=0.529
x 10^{-10} m allows you not to memorize all of h, e, and m_{e}.
From a knowledge of Avogadro's number and the chemical definition of a
mole, you can get the atomic mass unit in g.

k_{B} = 1.38 x 10^{-23}
J/K

N_{A}=6.022 x 10^{23}
molecules/mole

h/2p
= 1.054 x 10^{-34} Js

e = 1.602 x 10^{-19}
C

m_{e} = 0.911 x 10^{-30}
kg

1 amu = 1.66 x 10^{-27}
kg

m_{B
}= 0.927 x 10^{-23} J/T (the Bohr Magneton)

In addition to fundamental constants, of course, you do have to memorize a few other numbers. The ones that come to mind are

0^{o}C=273.15 K

1 atm = 10^{5} Pa
(actually 1.013 x 10^{5} Pa, and 1 "Pascal" is 1 N/m^{2}.)

You probably have your own list of things you keep in your head, like 22.4 liters per mole at STP, which would enable you to find how many pascals pressure is one atmosphere from the ideal gas formula, if you remember what "STP" is.
