Density

• What is density?


  It is the amount of mass in a volume and it tells us how tightly matter is packed together
• How can you calculate density?

  Mass divided by volume
• What are the symbols of calculating density?

  p= m/v
• what are the units of calculating density?

  kg/m3 = kg/m3
• How do you can grams into kilograms?

  you divide by 1000
• How can you change kilograms to grams?

  you multiply by 1000
• Density x volume = mass
• density/mass = volume
• mass/volume = density
• Write the method to calculate the density of a regular shape

  Density = mass x volume

  volume = height x width x length

  mass = ( the mass shown on the top pan balance )
• Write the method to calculate the density of a irregular shape

  1. Use an eureka can and fill water all the way to the top of the sprout
  2. Tie a string on your object/mass
  3. lower your mass carefully into your eureka can
  4. wait till the water stops dribbling into your beaker and the calculate your results
• Write the method to calculate the density of a liquid

  1. Turn your top pan balence one and measure the mass of your measuring cylinder without the water inside
  2. Pour in the amount of water needed into your measuring cylinder
  3. measure the mass of the measuring cylinder with the water added
• solution density = 1.1g/cm(3)

  (pure water) = 1.0g/cm(3)

  sugar concentration = o.1g/cm(3)

  0.1g/cm(3) x 1000 ( 1000cm(3) in 1dm(3) = 100g/dm(3)
• What is the density of an object with a mass of 6kg and 3m(3)?

  Density = mass divided by volume

  6/3

  = 2g/kg
• What is the unit for mass?

  Kilogram/grams
• What is the unit for volume?

  m(3)
• What is the unit for density?

  The unit for density is kilograms per cubic meter (kg/m^3).
