density of the liquid = 0.786 g/mL
Explanation:
The mass of the liquid is equal to the final mass of the container minus the mass of the empty container.
The mass of the liquid = 81.35 - 62 = 19.34 g
The volume of the liquid = 24.6 mL
density = mass / volume
density of the liquid = 19.34 g / 24.6 mL = 0.786 g/mL
