SI unit of mass density is ____

2. SI unit of mass density is ____.

1. (J/(kg·K))
2. (Pa·s)
3. (kg/m³)
4. (m/s²)

Answer: C) (kg/m³)

Explanation:

Mass density represents how much mass is contained within a given volume of a substance. It is determined by dividing an object or substance's mass by volume. The resulting value indicates the concentration of mass within a specific amount of space. The SI unit of kilograms per cubic meter (kg/m³) is commonly used for mass density because it provides a standardized and consistent way to express the relationship between mass and volume.
