if the rock is as you say then you could turn it into 3cm cubed and a mass of 30 grams. that means that it is 1cm cubed and a mass of 10 grams, so that means the density is 10 g/cc,while water's is 1 g/cc , finally the rock is ten times heavier then the water.

Q: A rock has a volume of 30cm cubed and mass of 300 grams what is its density compared to density of water?

Density is 2 g/cm3

density = mass/volume = 2g/40cm3 = 0.05g/cm3

If the density of mercury is 13.546 g per cm cubed, the volume occupied by 999 grams of mercury is 73.7 cubic centimeters. papadantonakis.com/images/d/d0/Chem_101_Lecture_Notes_6.pdf

Area of cylinder base = pi x Radius squared (πr2) Radius is in centimeters (cm) Area is in centimeters squared (cm2) ---- Volume = Area x Height Area is in centimeters squared (cm2) Height is in centimeters (cm) Volume is in centimeters cubed (cm3) ---- Mass = Volume x Density Density is in grams centimeter cubed (g/cm3) Volume is in centimeters cubed (cm3) Mass is in grams (g)

Density = mass(in grams)/volume ( volume in centimeters cubed. cc ) 9.6 kilograms = 9600 grams 15 cm^3 = 3375 cc Density = 9600 grams/3375 cc = 2.84 grams/cubic centimeters ( or milliliters) ( real density of iron is 7.86 g/ml )

mass = density x volume Mass = 5 grams per centimeter cubed x 10 centimeters cubed = 50 grams

The density must be 22.5 GRAMS per cm cubed, not 22.5 cm cubed. Then, Density = Mass/Volume implies Mass = Density*Volume = 22.5 * 5.42 = 121.95 grams.

density = mass/volume volume = mass/density mass = density x volume Ex: V=40m cubed M=300g D=a M/V 300/40 = 7.5g _______ m cubed or D= 7.5 grams per meter cubed

density = mass/volume,so the density of your metal is:25/10 = 2.5g/cm3 (grams per cm cubed)

Density = Mass/Volume = 150/6 = 25 grams per cm3.

No. A gram is a unit of mass. Centimeters cubed is a unit of volume. A milliliter is equivalent volume to a cubic centimeter, though.Common units of density are grams/milliliter or grams/cm3, which are equivalent.

Density is 2 g/cm3

Density = 1.587 g/cm3

Just divide the mass by the volume.

Density = Mass/Volume Density = 112g/7.40cm3 = 15.1 grams per centimeter cubed

Density = mass/volume Density of the cube = 8g/2cm3 = 4g/cm3

density = mass/volume = 2g/40cm3 = 0.05g/cm3
