Question

You are provided with a piece of rock and common laboratory equipment. How will you proceed to find its density?

Answer 1

Answer:

Density = mass / volume.

 

mass of the given rock piece is measured using physical balance.

 

Let us take a measuring jar and fill water in it partially.  

 

By immersing the given rock piece in measuring jar using a piece of thread,  we can measure the displaced volume of water.

This displaced volume is the volume of given piece of rock.

 

By knowing mass and volume, we can  calculate its density

Answer 2

Answer:

D=M/V

e.g.if the rock weighs(mass) 15g and volume 10mg then answer is 15/10=5
