This is the density.
Its density.
The ratio of a mass to the volume of a large sample in which the mass
is homogeneously dispersed is known as the concentration.
But the ratio of the mass of a whole sample to the volume
of the whole sample is the density of the substance.
Density is the ratio of mass to volume.
In order to determine the density of an object, it is necessary to know: the mass, the volume of the substance, and the definition of density.
Density = mass (g)
volume (mL)
If the density of a substance and either mass or volume is known, volume or mass, respectively, can be calculated using either simple algebra or dimensional analysis. The density must be translated as a conversion factor.
Water
The normal pattern for most compounds is that as the temperature of the liquid increases, the density decreases as the molecules spread out from each other. As the temperature decreases, the density increases as the molecules become more closely packed. This pattern does not hold true for ice as the exact opposite occurs.
In liquid water each molecule is hydrogen bonded to approximately 3.4 other water molecules. In ice each molecule is hydrogen bonded to 4 other molecules.
Well, I'll try to answer. "Density" describes the "weight" or something of a material. For example, the higher density, the less things will float in it. Water's density is enough to support beeswax, but olive oil cannot support beeswax. Get it? Mass is the weight of a material. Just the plain weight. Like, a hammer could weigh 6 pounds, which would be the mass. Volume is the compasity. So, the volume could explain how much the substance's compasity is. Mass describes how much it weighs, and density determines what can float or sink in the substance without actually testing. If a substance has a higher density than another substance, then the first will sink in the second. I hope I helped a little bit. =)
Mass is very different from weight.
Mass tells us the amount of matter contained in an object or substance. Weight tells us the gravitational pull affecting the object.
Density is the relation between mass and volume.
D= mass/volume
It allows for calulation of the density. D=m/v
it allows for calucation of the density. d=m/v
(Mass) / (Volume) of a sample of a substance is known as the density of the substance.
That's the 'density' of the substance.
Note:
Before you make the measurements,
you need to break off a piece.
Its density.
u will need the density. density = mass / volume so mass = volume x density
The density of a substance is often expressed in units of grams per milliliter. If a substance with a volume of 60 ml weighs 85 grams the density is found by dividing the weight (85g) by the volume (60ml). This substance has a density of 1.42g/ml
It determines the mass of the substance per unit volume.
They would use density to measure the volume of a substance :)
density
Density is the mass of a substance divided by the volume of that same mass of substance.
When we divide the mass of a substance by its volume we get its density.
If the density of the substance is known, then you can calculate it. Density = Mass/Volume, so Mass = Density x Volume
The mass of a given volume of a substance depends completely on the density of the substance being analyzed. Density = Mass / Volume
Density of substance = mass of substance / volume mass of substance = density x volume
The density is measured by dividing the mass of the substance with it's volume. Density = Mass/Volume.
Density is the ratio of mass and volume.
Density = Mass/ volume
Density is mass divided by volume.
When we divide the mass of a substance by its volume we get its density.
density is mass divided by /volume so mass is density times volume
So they can determine the density of a substance. Density = mass/volume. Density can be used to identify a substance.
