To determine the density of a substance, you need to know its volume and mass.
Here's why:
1. Density is defined as mass per unit volume. So, to calculate the density of a substance, you need to know both its mass (how much matter it contains) and its volume (the amount of space it occupies).
2. The formula for density is: Density = Mass/Volume. This means that the density of a substance is determined by dividing its mass by its volume.
3. By knowing the volume and mass of a substance, you can calculate its density and understand how tightly packed the particles are within that substance.
So, in the context of determining the density of a substance, the correct answer is: d. volumen y masa (volume and mass).
