The density of a substance is its mass per unit volume, given by the mass divided by the volume. Density depends on the substance of concern and doesn't matter whether one has a little amount of it or a whole full of it. Therefore, the density of the two smaller pieces is now the same as the original density.
Answer:
0.42g/cm³ or 420kg/m³
Explanation:
1cm³ = 1ml
10 × 1cm³ = 10cm³
Density = Mass ÷ Volume
4.2g ÷ 10cm = 0.42 g/cm³
Density = 0.42g/cm³ or 420kg/m³
