Determining the Density of Plastics 1) Introduction ⦁ a) Purpose: Determine density of different plastics ⦁ b) Hypothesis: If density is related to the ratio of mass to volume‚ then density can be calculated by using the formula D=M/V. i. c) Background: Density is the physical property that can be used to help identify substances. D=M/V. mass= found using a balanc and labeled in grams and volume=graduated cylinder or taking ( lxwxh ) measured in mL or cm3 2) Materials ⦁ a) List -graduated

Equations were used to figure the molecular weight of the sugar‚ and the number of moles of sugar in the volumetric flask. There was also an equation to figure the Molarity‚ as well. As a result of the experiment‚ I now have a better understanding of the density of a concentration‚ and what Molarity is . Observations Data Table 8: Initial Concentration Chemical Mass (g)

which contains about 13% of the world’s population and supports high urban densities due to its strong manufacturing base. The final cluster is North-eastern USA/southern Canada‚ which has a rich agricultural base and natural resources of coal iron ore‚ natural gas and oil. Population densities within these regions are over 50 people/km2. There are also fourteen smaller clusters of population with population densities of 10-50 people/km2. Included in this group are eastern Australia‚ the islands
