Think carefully.

How is "a metric ton mass" defined ?

A metric ton is 1000 kilograms, mass not weight. Mass is a
measure of inertia, which is a fundamental property of matter.
Weight is a force, which isn't a fundamental property of
matter.

OK I just have never seen the term "ton" used with "mass" problems.
Then it's obvious that equal masses of two different density matls.
will have different volumes and hence bouyant forces due to air
displaced.
