Answer:

0.0939 moles Cu

Explanation:

To find the amount of copper in moles, you need to multiply the given mass (g) by the atomic mass (g/mol) of copper. The atomic mass is a ratio which represents the mass of copper per every 1 mole. The ratio should be arranged in a way that allows for the cancellation of units (grams should be in the denominator to cancel the units of the starting mass). The final answer should have 3 sig figs like the given value (5.97 g = 3 sig figs).

Atomic Mass (Cu): 63.546 g/mol

 5.97 g Cu            1 mole
------------------  x  ------------------  =  0.0939 moles Cu
