It depends on the way the question is asked. If you are dealing with a cubic or rectangular object, you measure the length, width, and height, and multiply them. If it is a spherical or irregularly shaped object, you could used water displacement to find its volume. If it's a liquid, you could use a graduated cylinder to measure its volume.
Density is units of mass per unit of volume.
Use a mass balance to find the mass then find the volume by V=mass/density.
Density = mass/volume To find mass when density and volume are known, multiply the density times the volume.
Mass divided by volume Ex. Mass: 12 Volume:3 Density:4 g/cm Hope this helps!
Measure out a specific volume of water, such as 100mL. Determine the mass of that volume of water. Density = mass/volume, so divide the mass by the volume, and you will have the density.
Density is units of mass per unit of volume.
Density = Mass / Volume Rearranging this gives: Volume = Mass / Density Mass = Density × Volume
mass = density ( )/cm3 multiplied by volume( )cm3
density = mass/volume mass = density x volume
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)
Find its volume. Divide the mass by the volume to get the density.
density is mass divided by /volume so mass is density times volume
Density = (mass) divided by (volume)Mass = (Density) times (volume)
Density = mass/volumeMass = (density) x (volume)Volume = mass/density
Density = Mass/Volume
mass divided by volume... mass/volume=density
Multiply them: density*volume = mass
