2014 Period 4 Lab #1: Density Determinations for Solutions Theory: The density of a sample of matter is very useful when trying to find the identity of an unknown substance. The units of density are quoted in (g/mL) for liquid samples of matter. For that reason if the volume is known of a liquid‚ determining its density is easily determined by weighing it accurately. Density can also be used as a tool for finding the concentration of solutions in some cases. The density is different in a substance

When someone touches
