What is the density of the solid object that is weighed and submerged in water? The object's weight is 8.24g and is placed in a beaker filled with 18.5 mL of water. When It is placed in the water, it rises to 23.1 mL.

Density (D) is the quotient obtained when mass (m) is divided by volume (v).

D = m / v

The volume is the difference of the volume read after and before the object is placed in the beaker,

v = 23.1 mL - 18.5 mL = 4.6 mL

Substituting the known values for the density,

D = 8.24 g / 4.6 mL = 1.79 g/mL

Thus, the density is approximately equal to 1.79 g/mL.
