You are given moles and need to find grams, the atomic mass of any element is in g/mol so just go to the periodic tables and Cu which is copper has a mass of 63.546 grams/ mole.
Then you know if you multiply Mole * g / mol the moles will cancel out and you will be left with grams
so .0420 mol Cu * 63.546 g / mole Cu = 2.669 grams
