What is the density of a material that has a mass of 32.0 g and a volume of 1.60 cm3

If 32 grams of a substance can fit into 1.6 cm³ of space, then
the density of the substance is

            (32/1.6) = 20 g/cm³ .

That's definitely some dense and heavy stuff you've got there.
A standard baseball made out of that stuff would weigh about
9.6 pounds !

The densest naturally occurring element on Earth is osmium, a
metal in the platinum family with a density of 22.6 g/cm³ ... double
the density of lead, and triple the density of steel !  Whatever you've
got there, it's almost up there with the densest element in nature.
