  4. I just answered a very similar question, just change the numbers and recalculate: The volume lost is 4570 cm³ – 2140 cm³ = 2430 cm³ (guessing that "lose" means other than the chunk) 2430 cm³ x 21.45 g/cm³ = 52123...

  8. Density ..... There are two ways to solve these problems. You can use the density equation or you can use the unit-factor method (aka dimensional analysis) since the density is a ratio of two equivalencies, and makes a dandy conversion...
