So this question is asking you to find the density of silver.
00:05
They give you the mass of a piece of silver, and then they put it in water, and then they show you the change in the volume of water, and they want you to find the density based on that.
00:16
So an important equation we're going to need here is what density is.
00:21
Density is mass over volume.
00:26
Okay.
00:28
So what are the two things we're going to have to find? we're going to have to find the mass, right? they give us the mass here, and then we're going to have to find the volume.
00:33
Now, how do we know the volume of the silver? we can define that by how much water it displaced.
00:41
So basically, if you've changed the volume of the water by a certain volume, then by adding the silver, then that is the volume of the silver.
00:51
The difference in the volume of water after you add the silver is the volume of the silver.
00:56
Because you've taken up that much space, which has pushed the water to a higher level.
01:00
All right...
