  5. 15. tells you how many places to move the decimal and in which direction
  6. 16. a ratio of an object's mass to its volume; (m / v)
  7. 18. mm
  8. 20. V; Final volume - Initial volume
  9. 22. using a graduated cylinder to find the volume of an irregular solid
  10. 23. when going from a smaller unit to a bigger unit (g --> kg)
  11. 25. moving the decimal point (the same as multiplying by 100)
  12. 26. the exponent for a base unit

  5. 6. count number of digits from right (Atlantic) to left starting from the 1st non-zero digit
  6. 8. any percent error greater than 5%
  7. 9. how close a series of measurements are to each other
  8. 10. measured in liters (l) for liquids or cm^3 (cm x cm x cm) for solids
