Chemistry density lab answers

Density. Density is a physical property that is defined as a substance's mass divided by its volume: density = mass volume ⇒ d = m v d e n s i t y = m a s s v o l u m e ⇒ d = m v. Density is usually a measured property of a substance, so its numerical value affects the significant figures in a calculation.
