The average size of a human cell varies quite a lot. a single nerve cell can be up to a meter long while a cheek cell averages about 50 micrometers or .05 mm. the average cell though is between 10 micrometers and 100 micrometers.
The Size of Atoms. The size of atoms can be estimated with the use of Avogadro's number along with the atomic mass and bulk density of a solid material. From these, the volume per atom can be determined. The cube root of the volume is an estimate of the diameter of the atom. For carbon, the molar mass is exactly 12, and the density is about 2 gm/cm^3. The estimated volume is then. and the estimate of the carbon atomic diameter is the cube root of that. This estimate is a bit small. It can be refined somewhat by considering the atoms to be spheres and packing them in different ways.
