A student had a 15 cm long glass stirring rod with a density of 1.500 g/cm3. They
accidently dropped it on the laboratory bench and it broke. One part was 10 cm long and
the other was 5 cm long. What is the density of the larger piece?

The density of the larger broken piece from the original piece would remain 1.500 g/cm3

Density

Density = mass/volume

The ratio of mass to the volume of a substance is constant.

Thus, for the long glass stirring rod, a reduction in the length means a reduction in its volume. Also, there would be a commensurate reduction in the mass of the glass rod.

At the end of the day, the ratio of mass/volume of the glass rod, be it the larger or the smaller piece, remains the same.

Thus, the density would remain 1.500 g/cm3.
