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
