Question

Earth inner solid core, which has a radius of 1278km and is a mixture of iron and nickel (Assume its all iron here) Has an estimated density of 13000 kg/m^3

The resulting density of the spherical volume is higher than what we measure iron to be naturally in our laboratories due to the immense pressure from the weight of the planets outer liquid core, its mantle and a bit of its crust. 5 sig figs and include the unit of measure

1. The volume of the inner core in its current compressed state _______ ___unit
2. The mass of the inner solid core is then _______ __
3. If the outer layers did not exist, the inner core would expand back to an uncompressed volume of ______ ______
4. The Differenec of volumes is ____
5. The pressure upon the inner core must then be ____ _
6. In multiples of our atmospheric pressure, this is equivalent to ___
