For solids that are not soluble or reactive in/to water.
Density = Mass (g) / Volume (mL)
first find the weight of the solid in grams on a scale. (Mass)
second fill a beaker or other liquid measuring apparatus, large enough to hold the solid, with water (DI is best)
third take note of the amount of liquid in the container (preferably in mL)
forth fully submerge the solid in the liquid and note the new amount of liquid in the container.
now subtract the first amount of liquid from the second. this will give the volume of the object (Volume)
Density = Mass/Volume D= M/V D= g/mL
The volume of the object.
Weigh the piece of maple (you've indicated it is about 10 grams) Completely submerge it in a liquid and measure the volume of liquid displaced Density = mass/(volume displaced) or about 10g/(volume displaced)
You use integration - you divide the object into lots of thin layers, and calculate area x thickness for each. If the area is irregular, you use integration once again for each: divide it into lots of thin strips, and treat each as a rectangle.
It is an irregular galaxy.
you devide the mass of the object by the volume e.g. the mass of the block = 360g the volume = 120cm3 to find the density you divide 360 by 120 which = 3 to find the volume of a block you times the height by the width by the lenth eg 6 (L), 5(W), 4(H) = 6x5x4 = 120
The volume of the object.
There is no general formula. Many times an object can be looked at as the sum of smaller parts for which a formula is known. Ultimately all shapes can be reduced to small polyhedrons and then summed.
To calculate the density of an irregular shaped floating object, you can measure its mass using a balance and then find its volume by submerging it in a known volume of water and measuring the water displaced. For a regular shaped floating object, you can simply divide its mass by its volume to find the density.
Yes
Density = (mass) divided by (volume)regardless of the substance, or the shape of the sample.
To find the density of a regular shaped object, you can calculate it by dividing the mass of the object by its volume. For irregular shaped objects, you would measure the mass of the object using a scale, then measure its displaced water volume when submerged in a graduated cylinder. The density can then be calculated by dividing the mass by the volume of water displaced.
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
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).
I am not positive but i think that a regular shaped object can be measured and an irregular can not Hope this helps :D
To calculate the density of an irregular shaped object like a key, you would first measure its mass using a scale. Next, you would measure its volume using a displacement method with water. Finally, you would divide the mass of the key by its volume to determine the density.
The displacement method is used to determine volume. However, if you know the density, the displacement test can give volume, which is used to work out mass by the formula m = dV
method usede to figure the volume of an irregular shaped object
