The density of the unknown liquid is 4.03 g/mL
Density is defined as mass per unit volume i.e
To obtain the density of the unknown liquid, we'll begin by calculating the mass of the unknown liquid. This can be obtained as follow:
Mass of cylinder = 31.46 g
Mass of cylinder + unknown liquid = 112.15 g
Mass of unknown liquid = 112.15 – 31.46
Finally, we shall determine the density of the unknown liquid. This is illustrated below:
Mass of unknown liquid = 80.69 g
Volume of unknown liquid = 20 mL
Density = mass / volume
Density = 80.69 / 20
Therefore, the density of the unknown liquid is 4.03 g/mL
