Required Pratical 5:Density

How do we find the density of a irregular object

1)Find the mass of the object using a balance

2)Fill the Eureka can with water

3)Place the object into the water. This will cause water to be displaced and flow out of the cab through the spout.

4)Measure the volume of water displaced.This volume is the same as the volume of the object

5)Use the equation Density= Mass/Volume

To convert g/cm3 to kg/m3 you have to

Multiply the g/cm3 value by 1000

How to find density of a liquid

1)Place a measuring cylinder on a balance and zero the balance

2)Pour 10ml of liquid into the measuring cylinder and record the liquids mass.

3)Pour another 10ml into measuring cylinder,repeating the process until the cylinder is full and recording the total volume and mass each time.

4)For each measurement use the formula density the density(1ml=1 cm³)

5)Finally take an as average of your calculate densities. This will give you a value for the density of the liquid.
