An Unknown Element Crystallizes...?

An unknown element crystallizes in a cubic unit cell with an edge length of 3.36A. It has a density of 33.89g/cm3. The atomic mass of the element is 193.5 amu. What is the mass of one atom in grams?

* I got 1.285x10-22g, but I think I messed up somewhere, I just dont know where.

Answer:
"The atomic mass of the element is 193.5 amu. What is the mass of one atom in grams?"

The rest of the information appears to be a red herring. Since we know the atomic mass of the element, the mass of one atom can easily be obtained:

(193.5g / mol) * (1 mol / 6.02*10^23 atoms)

This gives 3.213e-22 g/atom as the answer.
