Because the definition of density is (mass) divided by (volume), and they're not connected ...
two objects can have the same mass but different volumes, or the same volume but different
masses ... so you have to know both numbers to calculate the object's density.
Matter is anything that has mass and has volume. One property of matter is density. Density is the amount of mass in a given volume of a substance. It is a ratio of a substance's mass to it's volume. This can be determined by dividing the mass of a substance by its volume. So this is why density is mass over volume. For the purpose of answering this question, substance refers to elements, compounds, and mixtures. For elements and compounds, density is a constant and can be a defining property.
Because the very definition of density is mass per (divided by) volume.
D = M/V
Because that is the definition of density
Density is the mass of a substance divided by the volume of that same mass of substance.
Density is mass divided by volume.
Density is equal to the mass divided by the volume.
To find the density of a substance, you need to know its mass and its volume. The mass is usually measured in grams or kilograms, while the volume can be measured in cubic centimeters or milliliters for solid objects, or in liters for liquids. By dividing the mass by the volume, you can calculate the density of the substance.
Density=Mass/Volume (That is, Density equals to Mass divided by the Volume over the object)
Density is the mass of a substance divided by the volume of that same mass of substance.
Density of a substance = (mass of a sample of the substance) divided by (volume of the same sample)
The density of any substance can be easily calculated knowing that it is defined as the ratio of the mass of a substance divided by the volume it occupies.
In order to calculate the density of a substance, you must know the volume and the weight of a sample. Then the density is calculated as Density = (Weight) divided by (Volume).
volume/mass= density
If the density of the substance is known, then you can calculate it. Density = Mass/Volume, so Mass = Density x Volume
Density is mass divided by volume.
Volume of a sample = (its mass) divided by (its density)
Density is equal to the mass divided by the volume.
To find the density of a substance, you need to know its mass and its volume. The mass is usually measured in grams or kilograms, while the volume can be measured in cubic centimeters or milliliters for solid objects, or in liters for liquids. By dividing the mass by the volume, you can calculate the density of the substance.
Density = mass/volume.
The density of a substance is the ratio of its mass to its volume. So, I would measure the mass and volume of a substance to calculate density.
