I want to know the answer to the following question:
What percent of normal matter is hydrogen?
All the background I'm provided with is that "Hydrogen, as atomic H, is the most abundant chemical element in the universe, making up 75% of normal matter by mass and over 90% by number of atoms (most of the mass of the universe, however, is not in the form of chemical-element type matter, but rather is postulated to occur as yet-undetected forms of mass such as dark matter and dark energy).". Is that enough to answer the question?
Answer: yes
