A ball of mass 1.2kg and a volume of 35cm cubed is dropped from a height of 2m. Determine the height to which this ball will bounce.

If the collision with the ground is perfectly elastic it will bounce back up to 2m. Otherwise you have to know how squishy the collision was.

The density of the ball, 34 g/cm^3, is higher than that of any known material outside a star. Even uranium has a density about half that.

Did you make up that question? Perhaps someone is playing a practical joke with this question.

If you dropped that ball on concrete, it would probably leave send pieces of concrete flying, leave a crater, and bounce poorly.

drwls- so the answer cannot be determined?

Correct. An experiment would be needed to establish the fractional energy loss per bounce.
