@HurtHikes, I hope this answers your question,
According to Wikipedia, most Hydrogen is in the form of Atomic and Plasma states.
Throughout the universe, hydrogen is mostly found in the atomic and plasma states, with properties quite distinct from those of molecular hydrogen.
Intuition says that because, as this link says, 99.9% matter in the universe is plasma, most Hydrogen in the universe should also be present in Plasma state.
"99.9 percent of the Universe is made up of plasma," says Dr. Dennis Gallagher, a plasma physicist at NASA's Marshall Space Flight Center. "Very little material in space is made of rock like the Earth."
This link has the calculations to determine the amount of Hydrogen in Plasma in relation to the total amount of Plasma (if anyone is interested...)
Stars are made of relatively simple stuff. By mass, our Sun is 73% hydrogen, 26% helium, and only 1% of higher Z (atomic number) atoms.
X = mHnH / r = density of hydrogen / total density
Though I am not sure about the actual answer about the same, I will be grateful if anyone can point out to the right answer. And although I have made every effort into the removal and rectification of errors, If there are any errors in my answer, I will be grateful if anyone can point them out.
