Why is the density of water greater than the density of air given the same volume for each material?
The density of water is 1 g/cm3.The density of air is 0,001225 g/cm3.
The density of gold is 19.3 g cm3 The density of iron pyrite is 5.0 g cm3 If a nugget of iron pyrite and a nugget of gold each have a mass of 50 g what can you conclude about the volume of each nugget?
The nugget of gold has a volume of 2.6 cm3, and the nugget of pyrite has a volume of 10 cm3.
What is the density of barium chloride in water?
For low molar concentrations, the change in density is insignificant, but for concentrated solutions the density can increase up to about 1.3 g/mL≈130 kg/m3
What element has the density of 3.0 g?
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)
Which planet can the sun's density be compared to?
The Suns mean density is around 1.41 g/cm3, which is similar to Jupiters density of 1.33 g/cm3 and Uranus' density of 1.30 g/cm3.
What is the density of the the inner core?
The density of the inner core is estimated to be between 12.8 -13.1 g/cm3, the most dense Earth layer.
Why is the density of water greater than the density of air given the same volume for each material?
The density of water is 1 g/cm3.The density of air is 0,001225 g/cm3.
Is it true that weight and size is used to measure density?
To calculate the density, find the mass and the volume. Mass divided by volume = Density. Each substance has a different density. Density is measured in g/cc (solids) or g/ml (liquids).
What layer would a solid cube with 6-cm sides and a mass of 270 g float?
Volume of cube = 6^3 = 216 cm^3 Density of cube = 270 g / 216 cm^3 = 1.25 g cm^-3 This cube would not float in water as its density is greater than the density of water at 1 g cm^3
Is the bottom layer water or bromoform?
The lower layer is Bromoform, tribromomethane CHBr3 with the highest density (2.889 g/cm3), almost three times greater than of water.Trick:To simply find out if water is the lower or upper layer in a two-layer fluid system, you canadd carefully one drop of water at the top of the liquidwatch accurately the path of the falling drop and when it does 'dissolve'Then:when going down through the upper layer, then it will 'dissolve' in the lower, you may conclude the upper layer is NOT water. Orwhen 'dissolving' immediately in the upper layer then you'll conclude the upper layer is water.
In the extraction of tea with methylene chloride and water will methylene chloride be the upper or lower level?
Just compare the densities of both water and CH2Cl2. Water is less dense and will be in the top (aqueous) layer. CH2Cl2 is more dense and will be on the bottom (organic) layer. Density H2O = 1.00 g/cm3 Density CH2Cl2 = 1.33 g/cm3
The density of gold is 19.3 g cm3 The density of iron pyrite is 5.0 g cm3 If a nugget of iron pyrite and a nugget of gold each have a mass of 50 g what can you conclude about the volume of each nugget?
The nugget of gold has a volume of 2.6 cm3, and the nugget of pyrite has a volume of 10 cm3.
What has its own density?
Each material has its own density!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.
What is the density of barium chloride in water?
For low molar concentrations, the change in density is insignificant, but for concentrated solutions the density can increase up to about 1.3 g/mL≈130 kg/m3
A block of wood 3.0cm on each side has a mass of 27g what is the density of this block?
A cube, with 3cm sides, has a volume of 3x3x3 = 27cc The weight is 27grammes. Density = weight / volume = 27g / 27cc = 1g/cc = 1000Kg/M3 A relative density of 1.0 (same as water)
How do you convert 5.427 gcm3 into standard form?
if you mean 5.427 g/cm^3, just change the unit to g/mL, and it is standard for density.
Why is density used to help tell what something is?
Because every material has its own density. 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.
