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,
\(\rho=\dfrac{m}{V}\)
Here \(m\) is the mass of the substance and \(V\) is the volume of the substance.
Put the values in the above formula to find out the density of the given metal,
\(\rho=\dfrac{35.4}{3.11}\)
\(\rho=11.38\)
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.
