Mass Divided by Density

The density of the body is defined as the measure of the mass per unit volume of the object. And the mass or the weight of the object is equal to the measure of the force equal to the amount of gravitational force exerted on the object. In the following article we will see in detail about the topic mass divided by density.

More about Mass Divided by Density:

As described above the mass of the object is the measure equal to the force exerted by the gravitational force on the object and the density of the object is defined as the mass per unit volume of the object. The units for the mass are expressed in the S.I units as Kg while the density of the object is expressed as `"Kg/m^3"` . The density and the mass of the objects can be used to calculate the volume of the object. If we know any two values we can calculate the other values using the relation between these values.


The relation between the density, volume and the mass of the objects are related as,

The density of the object = "Mass of the object"/ "Volume of the object"

So the mass divided by the volume of the object gives the volume of the object.

Volume of the object = "Mass of the object"/"Density of the object" 

The standard international unit for the volume is m^3 . And for the density of the object the standard international unit is the "Kg/m^3" .

Example Problems on Mass Divided by Density:

1. Calculate the volume of the object if the mass of the object is 15Kg and the density of the object is "3Kg/m^3".

Solution:

The density of the object = "Mass of the object"/"Volume of the object"

Volume of the object = "Mass of the object"/" Density of the object"

   = 15/3

   = "5 m^3"

2. Calculate the volume of the object if the mass of the object is 100 Kg and the density of the object is "4Kg/m^3" .

Solution:

The density of the object ="Mass of the object"/"Volume of the object"

   =100/4

   ="25 m^3"Practice problem on mass divided by density:

1. Calculate the volume of the object if the mass and the density of the object are 25 Kg and 5"Kg/m^3" respectively.

    Answer: `"5 m^3"`
