Want this question answered?
density of 1.5 cm tall and mass of 1.0 g of a cube of a cork=mass/volume of cube== 1.0/(1.5*1.5*1.5)gm/cm3=.2963gm/cm3
Mass = Density x Volume Density = Mass ÷ Volume Volume = Mass ÷ Density
Density = (Mass) divided by (Volume) If you know the density and volume, then Mass = (Density) times (Volume)
density is mass divided by /volume so mass is density times volume
to get density you take mass divided by volume
Density = Mass/Volume = 62.8/40 = 1.57 g/cm3.
density = mass/volume = 2g/40cm3 = 0.05g/cm3
Density = Mass/Volume so the density is 120/40 grams per cm3 = 3 grams per cubic cm.
Volume of a substance is measured in cubic units and is given by dividing its mass by its volume. In this case it is not possible to find the density of the cork since 2.71cm2 is a measurement of an area.
Iron pyrite (FeS2) has a density of 4.8 to 5.0 grams per cm3. A piece of volume 40 cm3 would, therefore have a mass of volume*density = 192 to 200 grams.
There are multiple methods as to estimate the density of irregular objects. The cork can be cut into a cylinder form. Using the equation for the volume of cylinder, and density (D = mass/volume) the cork density can be approximated.
Density = (mass) / (volume) = 2.1/14 = 0.15 gm/cc
Density = Mass/Volume = 2/8 = 0.25 g per cm3
Mass = Density x Volume Density = Mass/Volume Volume = Mass/Density
density of 1.5 cm tall and mass of 1.0 g of a cube of a cork=mass/volume of cube== 1.0/(1.5*1.5*1.5)gm/cm3=.2963gm/cm3
Density = Mass / Volume Rearranging this gives: Volume = Mass / Density Mass = Density × Volume
Volume = mass / Density Mass = Volume * Density Density = Mass / Volume
