To determine

To Identify:The quantity which is mass per unit volume.

Answer to Problem 30R

Mass per unit volume is nothing but the dimension of density.

Explanation of Solution

Introduction:

Mass per unit volume is nothing but the dimension of density.

Density is the mass of a material substance in a unit volume.

Density can be expressed as,

  $d=\frac{M}{V}$.............(1)

Here $d$ isdensity, $M$ is mass, and $V$ is volume.

Densityis expressed in grams per cubic centimeter.

Conclusion:

Hence, mass per unit volume is nothing but the dimension of density.
