What is the formula for calculating the maximum dry density? In road subgrade construction, the sand method is used to detect the compactness. The wet density and water content of the soil are known, and the maximum dry density value issued by the laboratory is known, and the maximum dry density of the sample is calculated

The density p is equal to the mass m divided by the volume v. for example, if a ton of water is packed in a container with a volume of one cubic meter and is just filled without overflow, its density is 1000 kg / cubic meter

Formula for calculating dry density in ring knife experiment

What is the calculation formula of compactness and water content detected by earthwork backfill experiment? (using ring knife detection method) DC = dry density of fill ρ D / maximum dry density of compaction ρ Dmax; ρ d = ρ / (1 + 0.01 ω)

What is the density formula?
Methane:
Colorless and tasteless gas, ρ = 0.717g/l (S.T.P); extremely insoluble in water. (density formula: M = 22.4 ρ)
Excuse me, what does the density formula mean?

Density = mass divided by volume
ρ=m/V
Assuming that methane is 1mol, the volume is 22.4l and the mass is 16g
So ρ = 16 / 22.4 = 0.717
