The phrase "a typical density of" is correct and usable in written English.
It can be used when discussing the average or common density of a substance or material in a scientific or technical context.
Example: "The study found a typical density of 2.5 grams per cubic centimeter for the mineral sample."
Alternatives: "an average density of" or "a common density of".
If a bulk material is composed of nanoparticles, the decrease in grain size for the nanoparticles leads to a drastic increase in the density of grain boundaries, which can result in a typical density of 1019 interfaces per cubic centimeter.
A typical density of adherent cells isolated from L1 stage worms was 3.8±1.3×103 cells/mm2 (n = 2) spread over a total area of 200 mm2, yielding 7.8±2.4×105 total adherent cells, or approximately 70% of the cells in solution before plating.
After planting, at a typical density of 1500 to 2500 plants ha−1, each plant produces a single pseudostem with one fruit bunch of 20 40 kg harvested 9 14 months after planting.
Fig. 1B shows the RNAs that were present in the different fractions of a typical density gradient.
Before the impulsive phase the electron density of the X-ray plasmoid was already an order of magnitude larger than the typical density of the active-region corona.
The mass of lava accumulated in the summit crater of Shinmoe-dake is 3.8 × 1010 kg, assuming typical density of andesitic lava of 2.5 g/cm3.
The electron densities of umbrae and sunspot plumes appear to be similar to the typical density of normal quiet Sun regions at similar temperatures (Brosius and Landi 2005).
Figure 1a shows the morphologies of the quartz/Al-ZnO film/Al-ZnO nanostructures, indicating that the highly densified Al-ZnO hierarchical nanostructures are quasi-perpendicular to the substrate, and the typical density of the nanostructures is approximately 6 × 109 cm-2.
Oberon's density of 1.63 g/cm³, which is higher than the typical density of Saturn's satellites, indicates that it consists of roughly equal proportions of water ice and a dense non-ice component.
Its density of 1.71 g/cm³, which is much higher than the typical density of Saturn's satellites, indicates that it consists of roughly equal proportions of water ice and dense non-ice components; the latter could be made of rock and carbonaceous material including heavy organic compounds.
We found that in different cellular compartments the typical density of detections within 2000 frames of 25 ms ranged from ρ = 2×10−3 to 8×10−3 nm−2, which results in a theoretical maximal spatial resolution of 44 to 90 nm (or 62 to 126 nm for 1000 frames) considering a constant density probability [28].
