Capillary density within tissues varies directly with tissues' rates and metabolism.
Capillary density in tissues varies with tissues rates and metabolism. It also depends on fibers, partial pressure, oxygen concentration and consumption, and blood flow.
Density can be used to determine the mass and the volume of a given solid.
You cannot. You can determine the third variable if two are given but not determine two when given only one. You have to find some other way to first determine volume or density.
That all depends on the type of gas and volume given for the problem. We can't determine the mass and density of the gas cylinder if we are not given these info, which can also include pressure (because density varies based on that variable).
If you are asking for the equation that is used to find volume when given mass and density. It is V=m/d.

There is difference between relative density and density.Density: it is the ratio of total weight of given sample to the total volume of that given sample, for example soil.Relative density: it is the ratio of the two densities,field density to the laboratory density. this is particularly useful and is used in the fields as it is not possible to attain 100% density which we determine in the laboratory tests, as the laboratory tests are conducted in controlled environment and we can not do that in case of field because of vastness. also field density is less then the laboratory density.
Strictly speaking if the density is given then you don't need to find it.
By size I think you mean the volume. And no, you also need the density of the object. Which tells you how much a given size weighs.
The answer depends on the units in which the mass and density are given.
If you had an object whose composition was entirely unknown, you could not analyse its composition by density alone. There are an endless number of possible combinations of materials that would have any given density. However, in some circumstances density does allow you to determine composition. If for example, you have an alloy of copper and zinc, but you do not know the relative proportion of the two metals and you would like to find out, you could determine that proportion by measuring the density, since copper and zinc each have a different density, and the problem can be solved as a simple algebraic equation.
When density and volume are given, the formula for density can be used to determine the mass of the object. density = mass / volume mass = density * volume Assuming the object is on Earth, it can be assumed that g=9.80 N/kg. w= mg, or weight = mass * gravitational constant (of Earth) purely algebraically, weight = density * volume * gravitational constant.
