Some help to the problems:
  • Density is mass divided by volume
  • Cc is cubic centimeter (cm3)
  • Check unit conversions for volumes from the internet
  • 1 meter = 10 decimeters, but 1 cubic meter = 1000 cubic decimeters

I don't want to give answers, because I don't want rob you from the possible Eurake-moments ;)
