Final answer:
The density of the substance is 4g/ml.
Step-by-step explanation:
The density of a substance can be calculated by dividing its mass by its volume. In this case, the mass of the substance is 24g and the volume is 6ml. To find the density, we divide the mass by the volume:
Density = Mass / Volume
Substituting the given values:
Density = 24g / 6ml = 4g/ml
So, the density of the substance is 4g/ml.
