Question

An unknown material, with a mass of 54 gm, was submerged in water. The object occupied 14 gm of water. What is the density of the material?

Answer 1

Answer:

Density of unknown material = 3.86 g/cm³

Explanation:

Mass of unknown material, M = 54 gm

The object occupied 14 gm of water.

Volume of unknown material = Volume of 14 gm of water.

Density of water = 1 gm/cm³

Volume of 14 gm of water  

                 $V=\frac{14}{1}=14cm^3$

Volume of unknown material, V = Volume of 14 gm of water = 14 cm³

Density of unknown material    

                              $\rho =\frac{M}{V}=\frac{54}{14}=3.86g/cm^3$
