A relative density bottle can be used to find the density of a liquid directly. The r. d. bottle is weighed empty and it has mass, m. It is then filled with liquid and weighed and it has mass, m 1 . Finally it is emptied, dried and refilled with water and weighed again and has mass, m 2 . r.d. = Density of liquid Density of H 2 O = Mass of liquid Mass of equal volume of water = m 1 -m m 2 -m
