Question

a graduated cylinder was filled with 25.0 mL of liquid. A solid object weighing 73.5 g was immersed in the liquid, raising the liquid level to 43.9 mL. Calculate the density of the solid object.

Answer 1

displaced volume :

Vf - Vi = 43.9 - 25.0 => 18.9 mL

D = m / V

D = 73.5 / 18.9

D = 3.88 g/mL

Answer 2

3.89 g/mL

Step-by-step explanation:

The experiment makes use of Archimedes' principle, where the volume of a liquid displaced by an object, is equal to the volume of said object.

Thus, the volume displaced by the object is:

43.9 mL - 25.0 mL = 18.9 mL

• The volume of the object is 18.9 mL

Density is equal to the mass divided by the volume, so:

D = m/V = 73.5 g/18.9 mL

D = 3.89 g/mL
