The density of water changes when salt is added to it. Density is mass per volume. If salt is added to water, mass is increased but volume remains the same.

If 2 pure substances have the same density are they same substance?
No, at a different temperature and pressure the volume of any substance increases or decrease (depending on Temperature and Pressure). Also the severity of the volumetric change depends on the state of the substance. Because density=mass/volume and the volume changes while the mass doesn't the density WILL change slightly in solid phase, noticeably in the liquid phase and significantly in the gas phase regardless of weather or not the substance is pure
Why does the density of a substance not change no matter how much of the substance you have?
Because density is a "ratio".
What happens when a pure substance undergoes a chemical change?
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
Is The density of a substance is the same for all samples of the substance?
Not necessarily. The temperature of the samples would have to be the same. It can also vary with how pure the substance is.
Difference between pure and impure substance from density?
Of course, the densities are different.
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.
What is the only way the density of a pure substance can change?
By changing the temperature as you can't add anything to a pure 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.

How can you change density of a substance?
You can change the density of a substance by changing its volume. Density is equivalent to mass over volume. So changing the volume affects density.

What happens to the density of a given substance if you increase the amount of substance that you have?
No change: Density is a property of the substance (physical property), which is not changed by the amount of substance.
How does the volume and density of a substance change when it is heated?
The volume of a substance increases when heated, causing a decrease in density.
