Answer:
The mass of an average copper atom is [tex]1.0548\times 10^{-22}\ g[/tex]
Explanation:
Given:
The total mass of copper atoms, [tex]m = 63.5\ g[/tex]
Number of atoms, [tex]N=6.02\times 10^{23}[/tex]
Now, we are asked to find the mass of 1 copper atom.
We use unitary method to find the mass of 1 copper atom.
Mass of [tex]N[/tex] atoms = m
∴ Mass of 1 atom = [tex]\frac{m}{N}[/tex]
Plug in 63.5 for 'm', [tex]6.02\times 10^{23}[/tex] for 'N' and simply.
Mass of 1 atom = [tex]\dfrac{63.5}{6.02\times 10^{23}}=1.0548\times 10^{-22}\ g[/tex]
Therefore, the mass of an average copper atom is [tex]1.0548\times 10^{-22}\ g[/tex]
