Transcript

  • 1. Notes
  • 2. The student will: Accurately measure the mass and volumeof a substance using the proper measuringdevices Demonstrate how the density of asubstance is determined Describe how density can be used todetermine the identity of a substance
  • 3. General PropertyPhysical PropertyCharacteristic PropertyDensity
  • 4. Observable ormeasurableproperty ofmatter. Mass andVolume All matter hasMass & Volume
  • 5. Any observableproperty ofmatter. Color Texture Hardness Luster Etc.
  • 6.  A physical propertythat is unique to thesubstance, Acharacteristicproperty can be usedto identify thesubstance▪ Density▪ Boiling Point▪ Melting Point▪ Reactivity
  • 7. Density is aCharacteristicProperty it is auniquecharacteristicof a substance
  • 8. The density of a substance isconstant and is not dependenton the shape or size .
  • 9. Determined by the spacing between theparticles as well as mass of the particlesthemselves In general solids are more dense thanliquids Gasses are much less dense thanliquids
  • 10. The density of water (H2O)▪1 g/cm3= 1 g/mL▪If a substance has a density less thanwater it will float no matter what itsweight.
  • 11. The ratio ofthe mass of asubstance tothe volumeof asubstanceD = m/V
  • 12. When a liquid, density is written asgrams per milliliter (g/mL)When a solid, density is written ingrams per cubic centimeter (g/cm3)
  • 13. Calculate the Mass of the substance (g)▪ Calculate the volume of the substance(cm3)▪ Apply the formula for density (D=m/V)▪ Write density as g/cm3
  • 14.  Calculate the mass of the full container (mf) Calculate the mass of the empty container(me) Subtract the empty mass from the full massto calculate the mass of the liquid mf–me=ml▪ Apply the formula for density (D=m/V)▪ Write density as g/mL
