Final answer:
To find the density, divide the mass (1 x 10^4 kg) by the volume (2 m³), resulting in a density of 0.5 x 10^4 kg/m³. The correct answer is b. 0.5 x 10^4 kg/m³.
Step-by-step explanation:
The question asks about determining the density of a substance when the volume and mass are given. The formula to calculate density (D) is D = mass (m) divided by volume (V), which can be written as D = m/V.
For the given problem, where the volume is 2 m³ and the mass is 1 x 10⁴ kg, the density would be calculated as follows:
Density = (1 x 10⁴ kg) / (2 m³) = 0.5 x 10⁴ kg/m³
The correct answer is b. 0.5 x 10⁴ kg/m³.
