What is the range of pressure in earths interior where rock with a density range of 9.9-12.12g/cm3 is found?

As the pressure increases, the density increases (see image attached)
At the range of pressure of 0.2 to 1.4 millions atmospheres, the density will be 3.4-5.6 g/cm³
At the range of pressure of 1.4 to 3.1 millions atmospheres, the density will be 9.9-12.2 g/cm³
At the range of pressure 3.1 to 3.6 millions atmospheres, the density will be 12.8-13.1 g/cm³

So, the answer is at the range 1.4 to 3.1 millions atmospheres

Ifound this on google “your outer ear collects sound waves and reflects them into a tiny tube called the ear canal. at the end of the ear canal is a thin, skin-like membrane stretched tightly over the opening, called the eardrum.” i hope this you for what your looking for
