  1. Let’s Review • If the rock has a mass of 6.2g, and a volume of 1.8 ml what is the density? 1. Circle what they are asking for. 2. Square the data (numbers with units) they give you. 3. Use density triangle to write equation. 4. Plug in numbers with units (cross out any units on top and bottom) 5. Calculate 6. Check that your units are correct for what they want!

  2. UNITS • Units for Mass= _____________ • Units for Volume= _______ or _________ • Units for Density= _______ or __________

  3. Let’s review If a television set has a density of 32 g/ cm3 and a volume of 67cm3, what is the mass of the TV? If a stapler has a mass of 27g and a density of 19 g/ cm3, then what is the volume?

  4. If an ice cream cone has a mass of 51 g and a volume of 41cm3 what is the density? • If a basketball has a density of 11 g/ cm3, and a mass of 58g, then what is the volume? • If a pencil has a density of 3.6cm3, and the volume is 15 cm3 what is the mass?
