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.

What physical and chemical properties would you expect to find in two different samples of a pure substance?
Physically I would expect to find the same boiling and melting points, and the same density. Chemically, I would expect the same reactivity with other substances.
Should the density of Al be the same for all Al samples?
The density of pure aluminium is the same for all samples.
What are some ways the density of a substance can be increased and decreased?
The increase in concentration increases the density and decrease causes the decrease in density.
Where is the least dense layer at in water?
Well the density throughout the whole water substance is the same, adding substances increases its density the part added then spreads throughout the water
How do you calculate the density of a substance?
Density is the mass of a substance divided by the volume of that same mass of substance.
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.
The density of the substance is the same for all samples of the substance true or false?
Any sample size of a particular substance will have the same density.
Why do two samples with the same substance with the same volume HAVE to have the same mass?
Because they are of the same substance they have the same density density = mass/volume
Is it true that the density of a substance is the same for all samples of the substance?
No, as density also depends on the state of matter in the sample of the substance.
True or false the density of a substance is the same for all samples of substance?
False :3
What is the effect of shape on the density of samples of the same material?
it has no effect. density of a substance is the same no matter the size or shape of the sample.
Which is more dense 1 mL of water or 50 L of water?
The answer is: No. Density is a property of a substance, and doesn't depend on the size of the sample. Samples of different sizes all have the same density, as long as they're all samples of the same substance, their compositions are all the same, and the conditions are the same in every case. (Samples of ice and water have different density, because the conditions are different.)
Under the same conditions of temperature and pressure three different samples of the same uniform substance will have the same?
Density reason is that the density of a uniform material is constant Density is independent of the size and shape of the sample.
What physical and chemical properties would you expect to find in two different samples of a pure substance?
Physically I would expect to find the same boiling and melting points, and the same density. Chemically, I would expect the same reactivity with other substances.
What cube has a greater density 35 centimeters or 70 centimeters?
If they both have the same substance inside, then they both have the same density. If they don't both have the same substance inside, then we have to know what the substances are before we can figure out anything about the density of the cubes. Size has nothing to do with density.
Is the density of an object bigger in one piece or two?
The answer to that question is: No. The density of an object only depends on the substance its made of. If two samples are made of the same substance, then it doesn't matter if one is the size of a grain of sand and the other is the size of a battleship ... they have the same density.
Should the density of Al be the same for all Al samples?
The density of pure aluminium is the same for all samples.
