What is the density of an object that has a mass of 20g and volume of 8cm3?
Density = mass/volume = 20g/8cm3 = 2.5 grams per cm3
What is the density of a rock that has a mass of 22.4g and a volume of 8cm3?
Density = mass/volume Density = 22.4g/8cm3 = 2.8g/cm3 or 3g/cm3 if significant figures are considered.
What is the density of a cube volume of 8cm and mass of 4g?
Density = mass/volume = 4g/8cm3 = 0.5g/cm3
What is the density of a cube with volume of 8cm3 and mass of 50g?
density = mass/volume = 50g/8cm^3 = 6.25 g/cm^3
What is the density of a piece of cork that has a mass of 0.650 g and a volume of 2.71 cm2?
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.
How to determine the density of an irregular cork?
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.
What would be the density of a piece of cork that has a mass of 2.1g and a volume of 14mL?
Density = (mass) / (volume) = 2.1/14 = 0.15 gm/cc
What is the density of a block that has a volume of 8 cm3 and a mass of 16 g?
16g/8cm3 = 2g/cm3 or 2x106g/m3
What is the equation for mass volume and density?
Mass = Density x Volume Density = Mass/Volume Volume = Mass/Density
How do you calculate the number of atoms in a block of aluminum that is 2 cm x 4 cm x 1 cm?
Volume of block = 8cm3. The density of Al is 2.7 g/cm3 Density = mass/volume Mass=Density*Volume Mass= 21.6g 21.6g Al *(1mole/26.98g) = .8 moles Al .8moles*(6.022*1023atoms/mole) = 4.82*1023 atoms
What is the density of a 64-g iron cube that displaces 8 mL of water?
Depends what metal. If I might add to the above, you cannot calculate the density of a substance without knowing its mass (weight) and its volume, since density is mass per unit volume. On the other hand, if you know the type of metal, and that it is pure, you can simply look up the density in a table since the density of all substances is constant for that substance, regardless of the weight or volume of the sample.
What is the density of 1.5 cm tall and mass of 1.0 g of a cube of a cork?
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
