1. Calculating Density Worksheet Review

2.  1. How close the particles are in a substance. Or how much mass fits in a certain space.  2. Density is “owned” by matter, if it’s matter it has a specific density that belongs to that type of matter.  3. m/v  4. D x V  5. m/D  6. You have to have your own answer  7. g/cm3  8. g/mL

3.  9. 32 g ÷ 43 cm3 =.74 g/cm3 float  10. 6cm x 3 cm x 11cm = 198 cm3 Density = 32 g ÷ 198 cm3=.16 g/cm3  11. Density  12. 32 g ÷ 28 cm3 = 1.14 g/cm3  13. Volume  14. 46g ÷19.32 g/cm3 = 2.38 cm3  15. 95 g ÷ 950 mL = 0.1 g/mL or 0.09 g/mL  16. First find the volume by subtracting the starting volume from the ending volume in the cylinder. 73 mL – 42 mL= 31 mL but this is a solid so change mL to cm3 31 cm3 now do the math to find density.  64g ÷ 31 cm3 = 2.065 g/cm3

4.  17. 54 g ÷ 32 mL= 1.688 g/mL  18. Solid  19. Mass and volume  20. Tool – ruler Unit – cm3  21. 200 mL X.789 g/mL = 157.8 g  22. 8.4cm X 5.5cm X 4.6cm = 212.52 cm3 Density = 1896 g ÷ 212.52 cm3 = 8.92 g/cm3  23. 2500g ÷ 10.5 g/cm3 = 238.095 cm3  24. Mass = 250 mL X.8765 g/mL = 219. 13 g or 219.125 g  25. 454 g ÷ 2270 cm3 = 0.2 g/cm3  26. 0.6 g/cm3 X 1.2 cm3 = 0.72 g

5.  27. blank, not actually a question  28. 4725 g ÷ 350 cm3 = 13.5g/cm3 Mercury  29. 171 g ÷ 15 cm3 = 11.4 g/cm3 Lead  30. 148 g ÷ 40 cm3 = 3.7 g/cm3 Aluminum  31. 475 g ÷ 250 cm3 = 1.9 g/cm3 Bone  32. 680 g ÷ 1000 cm3 = 0.68 g/cm3 gasoline (you could change this to g/mL because gas is a liquid.)
