    1. The problem statement, all variables and given/known data

    A hydrogen atom is in the 3d state. Determine the orbital angular momentum.
    2. Relevant equations

    3. The attempt at a solution
    I already know how to figure this out and have an answer but WHAT ARE the units?! It's not kgm/s^2!
