What is the use of copper metal?

Due to their greater conductivity than aluminum materials, copper materials are used in electronic equipment. Copper replaces aluminum in silicon chips for connectivity and leads frames in integrated circuits and printed circuit boards.

Let us Calculate the mass of a single copper atom.

The given sample of copper has a mass of 63.5 g

The number of atoms of copper in the sample is=[tex]6. 02 * 10^{23 } atoms[/tex]

It is given that n=[tex]6. 02 * 10^{23 } atoms[/tex] number of copper atoms has a mass of 63.5 g.

So, the mass of 1 copper atom will be,

[tex]m'=\frac{m}{n}[/tex]

[tex]m'= \frac{63.5}{6.022 * 10^{23} }[/tex]

[tex]m'= 10.54 * 10^{-23}[/tex]g

[tex]m'=1.054 * 10^{-22}[/tex] g

Therefore, the mass of one atom will be [tex]m'=1.054 * 10^{-22}[/tex] g
