help me please !! science question!?

Question

writing:
suppose you found a small stone of irregular shape. design and describe the steps and procedures that could be used to measure the density of the stone. describe the equipment you would use and what steps you would follow.

thank you sooo muchhh :]

Answer 1

It's simple enough:
I'd get the mass of the stone using a standard electronic balance.

I'd measure the volume by filling a marked container halfway with water then fully immersing the stone in the water and measuring the change in volume in the container (this is the volume of the stone)

density = mass / volume

Answer 2

1. Weigh the stone to determine its mass.
2. You need a tank full of water with a small drain just above the water level. Drop the stone in the tank. The water displaced will run out the drain. Capture it in a graduated cylinder. This is the volume.

Mass/volume = density.

Edited : Apparently they do step 2 differently from the way they did it at my high school. You just drop the object into a graduated cylinder and measure how much the volume changes.
