  17. A supposedly gold nugget is tested to determine its density. It is found to displace 19.3 mL of water ( which means it has a volume of 19.3 mL) and has a mass of 371 grams. Could the nugget be made of gold?

    gold =19.3 g/cm3
    d=M/v

    371/19.3=19.2222 g/cm3

    • No
  18. Acetone (nail polish remover) has a density of .7857 g/cm3

    a.
    What is the mass, in g. of 28.56 mL of acetone?
    b. What is the volume, in mL, of 6.54g of acetone?
    • d=m/v
    • .7857= m/28.56

    a. m=22.54

    .7857=6.54g/V
  19. Acetone (nail polish remover) has a density of .7857 g/cm3
