Question

1. A glass stopper has a volume of 16cm³ and a mass of 40g. Calculate the density of the g/cm³ and in kg/m³ ?

2. Calculate the volume of a block with 0.4kg if the density is 16kgm-³ ?​

Answer 1

Answer: 1)40000kg/m^3

              2)0.025m^3

Explanation: 1)density formulae=mass/volume

(40/1000)/(16/1000000)

40000Kg/m^3

2)d=m/v

0.4/v=16kgm^3

0.025m^3

Answer 2

Answer: The answer to this question is-

Given-

             volume, V = 16 $Cm^{3}$

              mass, M = 40 g

∴ Density, D (g/$cm^{3}$) = $\frac{M}{V}$

                ⇒ D = $\frac{40}{16}$

                ⇒ D = 2.5 g/$Cm^{3}$

∴ Density, D (kg/$m^{3}$) = $\frac{M}{V}$

               ⇒ D = $\frac{0.04}{0.000016}$

               ⇒ D = 2500 kg/$m^{3}$

And , Given-

                     Mass, M = 0.4 kg

                     Density, D = 16 kg/$m^{3}$

∴ Volume, V = $\frac{M}{D}$

               ⇒ V = $\frac{0.4}{16}$

               ⇒ V = 0.025 $m^{3}$

               

Explanation:

Understanding each term separately is essential in order to comprehend the relationship between density and volume.

Density

Density describes how much mass an object can fit into its volume or how tightly objects are crammed into a given space. Solids have a high density, liquids have a relatively low density, and gases have a low density.

For instance, the density of iron is greater than the densities of water and air molecules.

Volume

The space contained within a closed, three-dimensional space is referred to as volume. It may refer to the area that a material or shape takes up.

A solid cube's volume is calculated using the formula V=length*height*width.

I believe you now understand how volume and density relate to one another.
