One-third of Earth's mass is primarily composed of the core, which consists mainly of iron and nickel. The core accounts for a significant portion of Earth's total mass due to its dense material. Additionally, the mantle, which surrounds the core, contributes to Earth's mass, but the core's density and composition are key factors in reaching that one-third figure.

Is it true that the core of the earth makes up about two thirds of the earths mass?

No, that statement is not accurate. The Earth's core accounts for about 15% of the Earth's total mass. The majority of the Earth's mass is contained in the mantle, which makes up roughly 84% of the Earth's mass, while the crust contributes a small fraction.
