Calculating mass of inner core in Kg when i only have the density

flower123

Homework Statement

SO i dont have the radius or the volume but i have an estimate of the density 14.5 10³kg m-3

The Attempt at a Solution

If density estimate is all you have, I can't think of anything. But perhaps that's not the whole question/problem?

what else would i need? Radius? The radius is 1221km sorry for the rush in my posting and leaving out the rather important bits!

And the total mass, or the density of the none core part, or the overall average density.
