Respuesta :

Density is mass/volume. You will find it to be 11.38 grams per centimeter cubed (cm^3).

Remember, volume is cubed.

The element is Lead (Pb)

Density of a substance is mass per unit volume. The density of the unknown metal is 11.38 g per cm cubed and the metal is Lead.

Given information-

The mass of the sample of a unknown metal is 35.4 g.

The volume of the sample of a unknown metal is 3.11 cm cube.

The density of the metal has to find out.

What is density?

Density of a substance is mass per unit volume. It can be given as,

[tex]\rho=\dfrac{m}{V}[/tex]

Here [tex]m[/tex] is the mass of the substance and [tex]V[/tex] is the volume of the substance.

Put the values in the above formula to find out the density of the given metal,

[tex]\rho=\dfrac{35.4}{3.11}[/tex]

[tex]\rho=11.38[/tex]

Thus the density of the metal is 11.38 g per cm cubed.

The Lead element has the density of 11.3 g per cm cubed which is almost equal to the given metal.

Hence the density of the unknown metal is 11.38 g per cm cubed and the metal is Lead.
