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 principle behind the method is to determine NA as the ratio between the volume of the unit cell of a crystal, measured by X-ray crystallography, and the molar volume of the substance.". Is that enough to answer the question?
Answer: yes
