Answer

The sinkfloat method is often used to identity the type of glass material found at crime scenes by determining its density. Several different types of glass of known density are placed into solutions of varying densities. Determine whether each glass piece will sink, float, or do neither when immersed in the given solution. Glass that will sink Glass that will float Glass that will not sink or float alkali zinc borosilicate with a density of 2.57 g/mL in a solution with a density ot 2.50 g/mL soda-lime with a density of 2.47 g/mL in a solution with a density of 2.47 g/mL borosilicate (Pyrex) with a density of 2.23 g/mL in a solution with a density of 2.30 g/mL alkali borosilicate with a density of 2.29 g/mL in a solution with a density of 2.62 o/mL potash soda lead with a density of 3.05 g/mL in a solution with a density ot 1.62 g/mL
