1 of 3 The shattered glass case at the scene of a jewelry store robbery was determined to be made of potash borosilicate glass, which has a density of 2.16 g/mL. A 2.636 g glass fragment was recovered from a suspect's clothing. When the fragment placed into a graduated cylinder filled with water, 0.864 mL of the water was displaced. Calculate the density of the was glass fragment. g/mL d = Does the glass fragment that was found in the suspect's clothing link him to the crime scene? not enough information to determine O yes no
