Take an amount of the substance and find its mass. The density is the mass divided by the volume.
Typical units would be kg / m3 or g/L. English units are usually in weight per unit volume such as pounds/cubic foot or ounces / gallon.
It's not exactly a "substance" but Density = Mass / Volume
Density is the ratio of the mass of a substance to the volume of the substance.
The relative density of a substance is the ratio of its density to the density of some standard substance. The standard substance for solids and liquids is water. Thus for solids or liquids: Relative density = denisty of substance (kg/m3) / density of water (kg/m3) Relative density therefore has no units, it is a number, and indicates only how many times more dense the substance is than water. The relative density of water is 1 or 1000 kg/m3.
The density is measured by dividing the mass of the substance with it's volume. Density = Mass/Volume.
Density of a substance = (mass of a sample of the substance) divided by (volume of the same sample)
No substance is calculated that way. Mass per unit volume is called the density of a substance or object, which is a property or unit of measure of a substance.
Density is the mass per unit volume of the substance and for any "lump" of the substance may be calculated by Mass/Volume in the appropriate units.
Density is a very important property which can be used to identify a substance. We can calculate Density by dividing mass by volume.Density is the measure of how compact something is. To calculate density, take the mass of the substance, and divide it by the volume of the substance.
It's not exactly a "substance" but Density = Mass / Volume
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.
Density measures how compact a particular substance is. It can be calculated by adding the weight with the volume of the substance. To figure out the density of sugar you must first know the weight and volume and then plug them into the equation: density = weight + volume.
1.Are there any differences between the calculated density and the experimental density of a substance? If so, why?
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).
The relation between mass(M), density(ρ) and volume(V) is given by: M = ρ x V. So mass can be calculated only if both density and volume are known. Density is a measure of amount of substance per unit volume, so mass can't be calculated until the volume of substance is known.
Density is the weight of an object per unit of volume. For instance, the density of gold is 19 grams per cubic centimeter. To calculate the density of an object divide the weight of the object by the volume.
The mass in a given volume can be calculated from the density of the substance. Density = mass/vol so mass = density x volume
Density is the ratio of mass to volume of a substance. d = rho = m / V Density generally depends upon the following : ( 1 ) Identity of the substance ( 2 ) Temperature ( 3 ) Pressure for gases
