I want to know the answer to the following question:
One other measure involved the molar volume of what element?
All the background I'm provided with is that "The CODATA value quoted here is based on three watt-balance measurements of KJ2RK and one inter-laboratory determination of the molar volume of silicon, but is mostly determined by a 2007 watt-balance measurement made at the U.S. National Institute of Standards and Technology (NIST).". Is that enough to answer the question?
Answer: yes
