density
The density (1,4 g/cm3) is a physical property.
Density of 1.738 g/cm3 at 20 oC is a physical property.
g is not a unit for density. g/cm3 is. At room temperature: Aluminum has a density of 2.7 g/cm3 Scandium 2.985 g/cm3 Bromine 3.1028 g/cm3 (liquid)
Examples: Solid - water - noble gasCopper has a density of 8950 kg/m3 = 8.95 kg/dm3 = 8.95 g/cm3.Water has a density of 1000 kg/m3 = 1000 g/L = 1.000 kg/dm3 = 1.000 kg/L = 1.000 g/cm3 = 1.000 g/mL.Helium has a density of 0.1785 kg/m3 = 0.1785 g/L = 0.0001785 kg/dm3 = 0.0001785 kg/L =0.0001785 g/cm3 = 0.0001785 g/mL.
Density equals mass divided by volume. so 68 cm3 / 31 g = 2.2 g/cm3 would be the answer...2.2 g/cm3
g/cm3
3 g/10 cm3 = 0.3 g/cm3 and this is the density, since density is expressed as mass/volume.
The density (1,4 g/cm3) is a physical property.
Density has units of g/cm3 or g/L
Density of 1.738 g/cm3 at 20 oC is a physical property.
g is not a unit for density. g/cm3 is. At room temperature: Aluminum has a density of 2.7 g/cm3 Scandium 2.985 g/cm3 Bromine 3.1028 g/cm3 (liquid)
It depends on the gemstone. Here are some densities of common gemstones: Diamond: 3.515 g/cm3 Ruby/Sapphire: 4.05 g/cm3 Emerald: 2.765 g/cm3 Amethyst/onyx: 2.625 g/cm3 Pearl: 2.71 g/cm3
5.5153 g/cm3
Density equals mass divided by volume. so 68 cm3 / 31 g = 2.2 g/cm3 would be the answer...2.2 g/cm3

density = mass / volume = 13 g / 5 cm3 = 2.6 g/cm3
An object with a mass of 579 g and volume of 30 cm3 will have a density of 19.3 g/cm3.
