How can you determine the density of an irregular shaped object?

Answer 1

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

Answer 2

Weigh the object using a balance scale.

To find its volume, fill a beaker halfway with water, drop the object inside, and see how much the water rises. the volume of the object will equal the volume of the water displaced.

Divide the mass by the volume of the object which equals density.

Answer 3

SO i did and experiment on a irregular shape object .and if you want to find the density of a marble you have to weigh it first on a tripple beam balance then you record what the mass was. then u use a clear container with the measurement on it then your going to do water displacement to find the value u put water in their an stop at any number yo like but for now it is ten(10) then when u put the marble in ther it went up to bars so it would be 12 so it was first at ten when you fill it now it is at 12 . so you subtract the older number from the newer number ex. 12-10 are 12-10 =2 so the density will be two

Answer 4

m=vd

Mass is the product of volume and density. Density is, therefore, the ratio of mass to volume. Calculate the mass of your irregular shaped object. Then place it in a container of water, such as a graduated cylinder, and note how much water is displaced. Make sure the object is not trapping air.

Divide the mass by the volume.

Answer 5

Measure a specific amount of water into a graduated cylinder. Place the solid into the water and record the final reading. The volume=final reading minus initial reading. Use a triple beam balance to calculate the mass of the solid. Density = mass/volume.

Answer 6

Displacement method:

1. Record the mass of the dry solid object

2. Put a known amount of water in a volume measuring device

3. Put the object in the water and measure the new volume

4. Subtract #2 volume from #3 volume

5. Use the mass and divide by the volume of #4 (since density is mass divided by volume)

Do not use a laboratory beaker as a measuring device as they are often up to 20% incorrect. In Step 2. above you could just use a plastic container with a hole in the side of it. Fill the container until you are satisfied it is absolutely filled up to the hole. Put in the irregular solid and and collect the overflow in a measuring device that is suitable for the size of the solid.

Answer 7

Displacement method

Answer 8

1. Take the irregular object and weight it.

2. Then take measuring cylinder and fill water in it.

3. Then mark the marking of amount of water in it.

4. Now take the stone and drop in the beaker.

5. Mark the marking on the beaker of the water risen.

6. Now subtract the initial volume of water and the water risen.

7. Now you will have the mass of stone and the volume of stone.

8. Now as we know the formula of density is mass/ volume

9. Divide the mass of the stone by the volume of the stone.

10. The answer that you will get will be the stone's density.

Answer 9

1. Take the irregular object and weight it.

2. Then take a measuring cylinder and fill water in it.

3. Then mark the marking of the amount of water in it.

4. Now take the stone and drop in the beaker.

5. Mark the marking on the beaker of the water risen.

6. Now subtract the initial volume of water and the water risen.

7. Now you will have the mass of stone and the volume of stone.

8. Now as we know the formula of density is mass/ volume

9. Divide the mass of the stone by the volume of the stone.

10. The answer that you will get will be the stone's density.
