Final answer:
The density of the substance is 250,000 kg/m³.
Step-by-step explanation:
The density of a substance can be calculated by dividing its mass by its volume. In this case, the substance has a mass of 500 kg and a volume of 2000 cm³. To calculate its density, we use the formula:
Density = Mass/Volume
Density = 500 kg / 2000 cm³
Converting cm³ to m³ by dividing by 1000000:
Density = 500 kg / (2000/1000000) m³
Simplifying the expression:
Density = 500 kg / 0.002 m³
Density = 250,000 kg/m³
Therefore, the density of the substance is 250,000 kg/m³.
