Final answer:
The density of iron is 10 g/cm³.
Step-by-step explanation:
Density is defined as the mass of an object per unit volume. In this case, we are given that the mass of the iron is 150g and the volume is 15 cm³. To find the density, we use the formula:
Density = Mass / Volume
Substituting the given values:
Density = 150g / 15 cm³ = 10 g/cm³
Therefore, the density of iron is 10 g/cm³. This result illustrates how tightly packed the iron's mass is within its volume, exemplifying iron's density as 10 g/cm³, a fundamental characteristic used in distinguishing and understanding various materials based on their mass-to-volume ratio.
