The Moon has an average density of 3.3 g/cm 3 . From this number, what can we infer about the composition of the Moon?

The Moon's average density of 3.3 g/cm³ suggests it is composed mostly of silicate minerals, similar to Earth's mantle, with some iron, but not as much as Earth, which has a higher density due to its larger iron core.
