Answer:

762.60 g

Explanation:

In order to convert from moles of a substance into grams, we need to multiply the number of moles by the substance's molar mass:

  • Moles * Molar Mass = Grams

With the above information in mind, we can use the data given by the problem and calculate how many grams are there in 12 moles of Cu:

  • 12 mol * 63.55 g/mol = 762.60 g
