Density is an intensive quantity which means it is independent of size. This can be seen from the definition of density. Density = mass/volume So if the sample size increases than so does the mass, but the density remains unchanged.

What effect does the amount of the sample of a substance affect its density?
it has no effect. density of a substance is the same no matter the size or shape of the sample.
Does the density of a substance change depending on how much of it you have?
No. Density is an INTRINSIC property, and as such it does NOT depend on the size of the sample.
Is the density of a kilogram of iron less than the density of 1 gram of iron?
No. That's the beauty of "density". It's a characteristic of the substance, and the size of the sample has no effect on it. As long as the sample is pure, a pinhead of it has the same density as a truckload of it.
Why density is the criteria for purity with respect to chemistry?
Mass and volume are extensive properties, which are dependent upon the size of the sample. A larger sample will have a greater mass and volume than a smaller sample. Density is an intensive property, which does not depend on the size of the sample. Density is a ratio of mass to volume, which does not vary with the size of the sample. The density of a larger sample will be the same as the density of a smaller sample.
What are the relationship of the density of a substance to the amount of that substance?
None. That's why density is such a useful concept. It's a characteristic of the substance, and doesn't depend on the size of the sample. A microscopic dot has the same density as a truckload of the same substance.
What effect does the amount of the sample of a substance affect its density?
it has no effect. density of a substance is the same no matter the size or shape of the sample.
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.
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 does the density of a substance not change with the sample size?
Density = mass / volume As sample size increases, both mass and volume increase in the same ratio.
Does the density of a substance change depending on how much of it you have?
No. Density is an INTRINSIC property, and as such it does NOT depend on the size of the sample.
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.

Is density size dependent or size independent?
size independent

Kelly has a sample of an unknown substance. Which properties of the substance will be the same no matter how large or small her sample is?
All intrinsic properties will be the same regardless of sample size. Some examples would be density, color, temperature, chemical reactivity, etc.

How is density a size-independent property?
Purely from a definitional sense, density is size independent because it depends on the substance in question, not how much of it you have. From a mathematical sense, density is mass/volume. If the mass is equally distributed throughout the volume, then half of the volume, for example would have half the mass, preserving the same value of density.
