$58.9\ g$ $Co$ has the greater number of atoms.

Work Step by Step

- 58.9g $Co$: Molar mass ($Co$) = 58.9g/mol Therefore: 58.9g $Co$ = 1 mol $Co$ - 58.9g $Cu$: Molar mass ($Cu$) = 63.5g/mol Therefore: $58.9g \times \frac{1mol}{63.5g} = 0.93$ moles. Thus: 1 mol $Co$ > 0.93 moles $Cu$ So: the number of atoms in 58.9 g $Co$ is greater.
