The mantle has about 80 times the volume of the crust and about twice the density. So, the mantle at least is more massive.
I would expect the core to be much more dense. The outer core has about 16 times the volume and the inner core is slightly less voluminous (80%) than crust. Still I expect that both are much more massive than the crust.

There is more mass at the bottom of the earth, also scientist have discovered that the minerals at the crust and below absorb a lot of water.

A lot less, actually. The earth crust is just a few dozen of kilometers (between 60 and 100) thick, while the earth radius is 6400 km.

no other wise it would most likely have a bigger density which would make it go down and the earth below come up which it hasn't.
