an empty density bottle weighs 21.8g.When fully filled with a liquid A ,it weighs 40.6g .If the volume of the density bottle is20ml,what is the density of liquid A?
Volume of the bottle, V=20 ml
Mass of bottle,m= 21.8 g.
When filled with liquid the bottle weighs 40.6 g
Therefore, Mass of liquid in the bottle, m = 40.6 – 21.8 = 18.8 g
Density of liquid = m / V = 18.8/20
=>0.94 g/ml
