What is the chemical Makeup of a CME or solar Flare?

Question

I'm looking for the ratio of each of the elements ie(75% hydrogen, 25%helium)

Answer 1

Wikipedia says,

"The material consists of plasma consisting primarily of electrons and protons (in addition to small quantities of heavier elements such as helium, oxygen, and iron), plus the entrained coronal magnetic field."

I assume small quantities means way less than 25%
