I want to know the answer to the following question:
The Avogadro constant is determined to be the ratio between what two factors in the X-ray crystal density method?
All the background I'm provided with is that "The X-ray crystal density method is primarily a method for determining the Avogadro constant NA but as the Avogadro constant is related to the Planck constant it also determines a value for h.". Is that enough to answer the question?
Answer: no
