The mass of a solid is 3.60 grams and it's volume is 1.8 cubic centimeters. What is the density of the solid expressed to the correct number of significant numbers

Respuesta :

Density is ratio of mass and volume.
therefore Density is equal to mass/ volume
but mass =3.60gand volume =1.8cm3
therefore density is equal to 3.60/1.8
density = 2.0gcm3

Taking into account the definition of density,  the density of the solid is 2 [tex]\frac{g}{cm^{3} }[/tex].

First of all, density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space. That is, density is a quantity referred to the amount of mass in a given volume of a substance or an object.

Being the relationship between the weight (mass) of a substance and the volume it occupies, the density is calculated as the quotient between the mass of a body and the volume it occupies, obtaining the expression:

[tex]density=\frac{mass}{volume}[/tex]

In this case, you know that:

  • mass= 3.60 g
  • volume= 1.8 cm³

Replacing in the definition of density:

[tex]density=\frac{3.6 g}{1.8 cm^{3} }[/tex]

Solving:

density= 2 [tex]\frac{g}{cm^{3} }[/tex]

Finally, the density of the solid is 2 [tex]\frac{g}{cm^{3} }[/tex].
