Question

Hydrogen makes up more than 90% of all of the atoms, which equals three quarters of the mass of the universe.

A. True
B. False

Answer 1

Hydrogen makes up about 92% of the Sun's atoms and 73% of its mass, which is consistent with the data found in Table 15.2.

Step-by-step explanation:

Hydrogen makes up about 92% of the Sun's atoms and 73% of its mass, which is consistent with the data found in Table 15.2. The Sun is primarily composed of hydrogen and helium, with hydrogen being the most abundant element in the universe. So, even though hydrogen atoms make up a small percentage of the mass compared to heavier elements, they still constitute the majority of the atoms.
