Final answer:
Population III stars are the earliest generation of stars that formed in the universe, and they are believed to have very low mass due to the low metallicity of the gas clouds from which they formed.
Step-by-step explanation:
Population III stars are the earliest generation of stars that formed in the universe. They are believed to have very low mass, with mass ranges typically below 0.8 times the mass of our Sun. These stars formed from primordial gas containing only hydrogen and helium, with very little or no heavy elements.
The low mass of Population III stars is due to the fact that they formed from gas clouds that had very low metallicity (low abundance of heavy elements). The presence of heavy elements can affect the collapse of a gas cloud and influence the size and mass of the resulting star.
Therefore, the statement that Population III stars should have had very low mass is true.
