How many moles of gold are equivalent to 1.204 × 1024 atoms?

Explanation:

It is known that the value of Avogadro's number is .

Therefore, calculate moles of gold atoms as follows.

    Moles of gold atom =

                                    =

                                    = mol

                                    = 1.99 mol

Thus, we can conclude that 1.99 mol of gold atoms are equivalent to atoms.

i think it's c. i'm not sure but i think so.

im not exactly sure but i think its b!
