Main Answer:
The density of the unknown liquid is 0.4 g/mL, calculated by dividing the given mass (200g) by the volume (500ml). Density represents the mass per unit volume of a substance.
Step-by-step explanation:
The density of a substance is calculated by dividing its mass by its volume. In this case, the mass of the unknown liquid is given as 200g, and the volume is 500ml. Using the formula density = mass/volume, we find that the density is 0.4 g/mL.
Density is a measure of how much mass is contained in a given volume. In this context, it indicates that for every milliliter of the unknown liquid, there are 0.4 grams of mass. This information is crucial in various scientific and industrial applications, such as identifying substances or determining their suitability for specific purposes.
Understanding density is fundamental in both physics and chemistry. It helps scientists and researchers characterize materials and substances based on their mass and volume properties. In practical terms, knowing the density of a liquid can be vital in fields like manufacturing, where precise measurements are necessary for quality control.
In summary, the density of the unknown liquid is 0.4 g/mL, indicating the mass of 0.4 grams for every milliliter of the substance. This numerical value is derived from the ratio of the given mass (200g) to the volume (500ml).
