The magnitude is simply the value /L/ from  eqn 362 with the /l/ values 
being determined from the mapping to the orbital.

s orbital -> l=0
p orbital -> l=1
d orbital -> l=2
f orbital -> l=3

so, for example, a 3d orbital should have angular momentum magnitide of 
Sqrt[6] hbar.

One parting point -- note that this problem is asking you about the 
magnitude of the total angular momentum and not asking you anything 
about resolving the momentum into it's vector components.
