Describe a way to measure the density of a small insoluble object that is denser

Question

Describe a way to measure the density of a small insoluble object that is denser than water, using only a scale, water, and a graduated cylinder. (This is not in the lab report, but you should be able to figure this out.)) What does the variable C, stand for? Write a useful equation that includes G-. No numbers are needed. in the course of this lab, you will make several cooling plots. How can one find T, using a cooling plot? Why must one use a cooling plot to measure T, ? (See step 7 in the procedure).

Explanation / Answer

The density just means how much mass per volume.

That means mass (M) divided by volume (V).

It's easy to find the mass M. You can just weigh something on a scale. So the trick is to find the volume V of the irregularly shaped object. There's a way to do this.

1)Take some water in graduated cylinder, enough to submerge your object.

2)Mark the level of the water in cylinder.

3)As the object goes into the water, it will force the water up in the cylinder.

4)Mark the level of the water when the object is completely under.

5)Now take the object out. You can pour water in from a measuring cup (say one marked in liters) to see how much is needed to fill from the lower mark to the upper mark.

6)That volume is the same as the object's volume.
  

Now divide Mass/Volume to find out density.
