The density of a substance is the same for all samples of the substances?
Density is simply the mass divided by volume. This means that it is the amount of the substance in a specific unit of space. Because a pure substance indicates that it is exactly that, a substance made of a specific combination of elements, it will always have the same density because those elements can only take one form in order for it to be pure.
Does the density of a pure substance affect the drawing of the phase diagram?
No, the density of a pure substance does not affect the drawing of the phase diagram. Phase diagrams are typically determined by the temperature and pressure conditions at which different phases of a substance coexist, regardless of density.
Does pure substance float on pure water?
Whether a pure substance floats on pure water depends on its density compared to that of water. If the substance's density is less than that of water (approximately 1 g/cm³), it will float; if it is greater, it will sink. For example, ice (a pure substance) floats on water, while metals like iron will sink.
Who A droplet of pure mercury has a density of 13.6 gcm3. What is the density of a sample of pure mercury that is 10 times as large as the droplet?
The density of a substance is an intrinsic property that does not change with the size of the sample. Therefore, even if the sample of pure mercury is 10 times larger than the droplet, its density remains the same at 13.6 g/cm³.
What happens when a pure substance undergoes a chemical changes?
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped
If Using density how dowe determine if a substance is pure or not?
If a substance is not pure, the density may, or may not, change, compared to the pure substance.
How is the density of a pure substance affected if the mass and or volume are changed?
The density of a pure substance remains constant regardless of changes in mass or volume. Density is a physical property that is inherent to a substance and is calculated as mass divided by volume. As long as the substance remains the same, the density will not change.
A droplet of pure mercury has a density of 13.6 gcm3. What is the density of a sample of pure mercury that is 10 times as large as the droplet?
The density of a sample of pure mercury that is 10 times as large as a droplet will remain the same at 13.6 g/cm3. Density is an intrinsic property of a substance that does not change with the amount of the substance.
What are two reasons why density is a useful property identifying substances?
Density can tell you how "pure" a substance is. Since each substance has a specific density in its "pure" state, having no other substances in its composition, by measuring it density you can tell how pure the mineral or substance is, 99.9% pure gold.
What are two reasons why density is a useful property for identifying substances?
Density is specific for each substance. Also the measurement is generally simple.
Difference between pure and impure substance from density?
A pure substance has a specific density that remains constant regardless of the amount of substance present. An impure substance may have a density that varies depending on the amount and type of impurities present in the substance.
What does a substance mean?
A pure substance is a substance that cannot be separated by means of physical separation but only by chemical. It is a change in time.
If 2 pure substances have the same density are they same substance?
Not necessarily. Two pure substances can have the same density but still be different substances. Density is an intensive property that is dependent on the substance's mass and volume, not its chemical composition.

Will diffrent volumes of the same substance have the same density or different densities?
Different volumes of the same substance will have the same density. Density is an intrinsic property of a substance, which means it is constant regardless of the volume it occupies. This relationship is expressed by the formula density = mass/volume.
Is water a pure substance if it is mixed with something?
Only if the mixture is a physical, not chemical, change.
