Density = mass/volume = 16 of some units/25 ml = 0.64 some units per ml - which is quite a useless measure if you don;t know what the units of mass are!
scientists have proven that it is frogs.
Density = (mass) divided by (volume)regardless of the substance, or the shape of the sample.
Measure the displacement of water when the object is submerged in water. This gives the volume ; then weigh the object and divide the weight by the volume to get the density.
Measure the displacement of water when the object is submerged in water. This gives the volume ; then weigh the object and divide the weight by the volume to get the density.
Measure the volume of the object which is same as the volume of the displaced liquid in which that sinks. And measure the mass of the same object from a weighing machine. then use density = mass/volume
First you get the object mass by weighing it.Then you get its volume by immersing it in a scaled water container and see the increase in water volume which gives the object volume.Then you divide the mass by the volume to get the object density.
its volume can only be messured by displacement. it is difficult to equaly devide. it can be difficult to determine density if you are trying to determine the density of the material, not the object.
measure the volume of liquid that the object displaces
Weigh the object. Determine the volume. Divide the mass by the volume to get the density. To get the volume of an irregular shaped object can be challenging especially if there are cavities (holes) in it. submersion in a liquid or powder of known volume might be possible. Measure the difference in the volume of the liquid and the liquid + the object (making sure the object is entirely below the surface of the liquid and that any cavities are filled).
The same units are used for regular or irregular objects - for example, kilogram per cubic meter.
A measuring cup or graduated cylinderWater or other liquid to place the solid in
You need to do the water displacement method. The water displacement needs a graduated cylinder and water.
