• To Find the Density of a Solid Object

  1. Use a balance to measure its mass

  2. For some solid shapes, you can find the volume using a formula

  3. For a trickier shaped-solid, you can find its volume by submerging it in a eureka can filled with water

  4. Record the volume of water in the measuring cylinder

  5. Plug the object's mass and volume into the formula to find its density
• To Find the Density of a Liquid

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

  2. Pour 10 ml of the liquid into the measuring cylinder and record the liquid's mass

  3. Pour another 10 ml into the measuring cylinder and record the total volume and mass

  4. Repeat this process until the measuring cylinder is full

  5. For each measurement, use the formula to find the density

  6. Take an average of your calculated densities to get an accurate value for the density of the liquid
• Eureka cans help find the volume of irregularly shaped solids
