How do you calculate particle size from surface area and density?

Without going into a long derivation, the diameter (D) of a particle (in microns) can be estimated from a material with a known surface area (SA, in m2/gram) and density (p, in gram/cm3) using the equation D = 6 / (SA * p). As an example, an aluminum powder with a surace area equal to 0.5 m2/gram and a density of 2.7 gram/cm3 would be 4.44 microns (D = 6/(0.5*2.7) = 6/1.35 = 4.44) Assumptions: You are assuming that you have equi-sized, spherical particles (which is never the case, but allows for a good approximation).

How do you calculate the volume of a triangle if you only have the height and density?
A triangle is a flat area, therefore it has a surface area, not a volume. Density is unrelated to the problem; you would need some additional information to calculate the surface area.
What is the difference between surface and density?
You cannot use surface area to calculate density. Density is a calculation comparing TOTAL area and weight of an object. In short you must use the total volume of the object when calculating the density.
How do you Calculate mass with surface AREA?
You cannot These are different concepts. you need a volume and density to calculate mass, surface area provides neither (a cube and a sphere with the same surface area have different volumes and, had they been made of the same material, would have different masses).
How do you calculate density from surface area per m2 and number of species ie density of epiphytes per m2 of trunk from having the surface area of the trunk and number of epiphytes on it?
mass divided by volume asses mass divided by volume asses
Why does reducing solute size particle size increase the speed at which the solute dissolves in water?
For the amount of material in the particle the surface area of a small particle is greater than a larger particle. Said another way, the surface area per unit volume is greater for a smaller particle. Dissolving speed is related to the surface area. Therefore a smaller particle dissolves faster than a larger particle.

How do you compare the surface are to volume ratio of cells of different size?
You need to:* Calculate the surface area * Calculate the volume * Divide the surface area by the volume
How do you calculate surface area to volume?
surface area divided by volume
How could you calculate the surface area of a shape?
To calculate the surface area of a shape find the area of each side, and then, add all of the areas together. The sum of the areas is the surface area.
How do you calculate surface area to volume ratio?
You measure or calculate the surface area; you measure or calculate the volume and then you divide the first by the second. The surface areas and volumes will, obviously, depend on the shape.
What is the effect of dividing a big particle into smaller ones on the total exposed surface area?
The total surface area increases.
What is the formula to calculate surface area?
It depends on the shape whose surface area you are interested in.
