Answer:

1 atom of Cu has a mass of 1.055× [tex]10^{-22}g[/tex]

Explanation:

1 atom of copper must be converted in moles to express it as a quantity that can be converted into grams (our second step).

Avogadro's Number( 1 mole = 6.022 x[tex]10^{23}[/tex]particles and the relative atomic mass of copper( 1 mole of copper = 63.546 g ) are the equalities required to make this conversion.
