Question

Mass of an empty density bottle is 21.8 g when completely filled with water it is 46.8 g and when completely filled with another liquid it is 40.6 g. Calculate the i) Volume of the density bottle ii) relative density of the liquid​

Answer 1

i) mass of water = 46.8-21.8 = 25g

density of water = 1 g/cm^3

volume of water = mass of water

Volume of bottle = 25 g/cm^3

density of bottle = M/V = 21.8 / 25 = 0.87 g/cm^3

ii) mass of liquid = 40.6 - 21.8 = 18.8 g

density of liquid = 18.8/25 = 0.75 g/cm^3

relative density = density of liquid/density of water

= 0.75/1 = 0.75
