Density Procedure..?

Question

What are the PRECISE (every little step) to figuring the Density of both a solid AND a liquid (two different procedures)? (D=M/V) For ten points pleaseee?

Answer 1

Solid - take a sample of the solid. Weigh it. Fill a graduated cylinder with water. Put the sample in the water. Measure the change in volume of the water. This change in volume is the volume of the sample. Now you have the measurements you need to calculate the density.

Liquid - take a known volume of liquid and put into a container of known weight. Weigh the liquid and the container. Subtract the mass of the container. This is the mass of the liquid. Now you have the volume and mass of the liquid you can calculate the density.

If you need to be really precise I would suggest taking the temperature of the liquids.

Answer 2

1. Tare an appropriate empty container.
(Weight a clean, empty container. Either reset the balance
to zero and remove the container or write down the mass
of the empty container - the tare)
2. Pour add compound to an appropriately-tared container
3. Weigh the container + the added compound
4. Subtract mass obtained in Step 3 from that obtained in Step 1.
5. Write down this mass for use later.

IF THE SUBSTANCE OF INTEREST IS A SOLID...
6. Fill an appropriately-sized graduated cylinder about halfway
with water. Record the volume of liquid alone.
7. Add the solid to this same graduated cylinder. Record
the "new" volume as read from the graduated cylinder.
NOTE: If any splashing or overflow results, restart with a
lower volume of water or a larger cylinder.
8. Subtract the volume found in Step 7 from the volume found
in Step 6.
9. Now calculate the density by dividing the mass you wrote
down in Step 5 by the volume you found in Step 8.

IF THE SUBSTANCE OF INTEREST IS A LIQUID...
10. Pour the liquid sample into a graduated cylinder (of
appropriate size) and measure its volume.

11. Divide the mass found in in Step 5 by the volume you
found in Step 8. Note: With wisdom and care, you can
determine the density of a liquid in the same grad. cylinder
that you measured its volume in. All depends on sizes of
containers, volume of liquid, and capacity of balance.

Voila...

Answer 3

For a non porous solid

Weight sample in air
weigh the same sample under water
the difference in weight is the weight of water displaced by your sample
Since water's density is 1 g/cc, the difference in weight is also your volume in cc
now you have a mass and a volume to calculate density

for liquids you can directly measure the volume in a graduated cylinder, or you can use a specific gravity indicator device. Specific gravity is just a ratio between the density of one substance over the density of water.

Answer 4

Technically is DOES substitute, on the grounds that water isn't completely incompressible. And if your water isn't organic water, it maximum particularly adjustments, on the grounds that dissolved salts or mixed sediments settle in greater advantageous concentrations at decrease depths. one thank you to do it somewhat is to apply buoyancy. Get an merchandise that's a diverse sinker of prevalent mass m and prevalent quantity V. you recognize Earth's gravitational field is g, anticipate it would not substitute and anticipate a cost of 9.8 N/kg for it. carry it on a string, and use a spring scale to degree the stress interior the help string T. develop the help string prevalent depths d, and record how stress varies. favourite instruments are: m in kg V in meters^3 T in Newtons d in meters if your gadgets are not calibrated in favourite instruments, please pre-convert to the popular instruments. next, right here is the formula you could derive from Archimedes theory for the density of the water at any length intensity. rho_w = m - T/(V*g)
