Respuesta :
The density of a substance that has a mass of [tex]20 g[/tex] and a volume of [tex]10 mL[/tex] is [tex]2 g/cm^{3}[/tex].
What is density?
Density of substance is defined as its mass per unit volume. Density gives information about how tightly the substance is packed together. The formula for density is
[tex]d =\frac{m}{V}[/tex]
Where,
[tex]d =[/tex] density
[tex]m =[/tex] mass
[tex]V =[/tex] volume
Unit of density is grams per cubic centimetre.
What are uses of density?
One of the most common uses of density is in how different materials interact when mixed together.
- Wood floats on water because it has a lower density than water, while an anchor sinks as the metal has high density.
- Balloons filled with helium gas float because the density of the helium is low than the density of air.
What is Specific Gravity?
Specific Gravity is the ratio of the substance's density to the density of water. An object having specific gravity less than one will float in water, while a specific gravity greater than one will sink.
Given
[tex]m = 20g[/tex]
[tex]V = 10 mL= 10 cm^{3}[/tex]
The density of substance is
[tex]d =\frac{m}{V}\\d =\frac{20}{10}\\d = 2 g/cm^{3}[/tex]
Hence, The density of a substance that has a mass of [tex]20 g[/tex] and a volume of [tex]10 mL[/tex] is [tex]2 g/cm^{3}[/tex].
