Determine its volume by how much water it displaces,
then divide mass by volume
Mass is measured by density multiplied by volume. In order to figure out a mass of a rock, one must know its density and its volume measurements.
Density = Mass / Volume Rearranging this gives: Volume = Mass / Density Mass = Density × Volume
You need the mass and volume to calculate the density
You have to know two out of three ... mass, volume, density ... then you can find the missing one. If density is missing . . . Density = (mass)/(volume) If mass is missing . . . Mass = (density) x (volume) If volume is missing . . . Volume = (mass)/(density)
Density= mass/volume volume = mass/density
Find the mass using a scale. Find the volume by the water displacement method. Divide mass by volume and that equals density.
density = mass divided by volume = 100/25 = 4 grammes per cubic centimetre.
Mass is measured by density multiplied by volume. In order to figure out a mass of a rock, one must know its density and its volume measurements.
The rock's density is 3 g/cm3
mass = density ( )/cm3 multiplied by volume( )cm3
Density is the amount of matter per cubic unit. So, in order to find density, you need to divide the mass of the object by its volume. For an example: if a rock has a volume of 2 cubic meters and it has a mass of 10 kg., then you would divide 10 by 2 and you get the density of the rock (i.e., 5 kg/meter^3). Density = Mass / Volume
The answer depnds on the density of each rock. If they are different denities thenthere is a chance that the 1mL rock may have more mass. If they have the same density then the 4mL rock will have more mass
Find its volume. Divide the mass by the volume to get the density.
The simplest way is to use the formula: P = m / V Density = mass / volume So to calculate the denisty of the rock you will have to find out how much it weighs and how much volume it occupies. You can measure the weight by placing the rock on a weighing scale, this will give the weight in grams. You can determine the volume by submerging the rock in a measuring cup partially filled with water and measuring how much the volume increases. This will give the volume in cm3 Now use the formula to calculate its density in g/cm3.
Density = Mass / Volume Rearranging this gives: Volume = Mass / Density Mass = Density × Volume
Density = mass/volumeMass = (density) x (volume)Volume = mass/density
Density is mass over volume, so divide 25 by 5(25 / 5) = 5 g/cm3 or g/cc
