In order to find the amount of atoms you have to find the moles then multiply by Avogadro's Constant (L)

mol = [tex] \frac{MASS}{Molar Mass}[/tex]
 
       = [tex] \frac{237 g}{63.55 g/mol} [/tex]
       
       =  3.73 mol

Number of atoms of Cu =  mol × L
                
                                      = 3.73 mol × (6.02 × 10²³)
                          
                                      = 2.245 × 10²⁴ atoms of copper
