Which has more atoms, 2 moles of helium or 1 mole of
gold?

If 1 mole of atoms is 6.02 x 1023 atoms, then 2 moles of atoms would be equal to 1.2 x 1024 atoms. And if there are 6.022 X 1023 atoms in one mole of gold. Then find ur answer would be?

   (1.2 x 1024)         (6.022 X 1023

          ∨                            ∨

   (convert)  (Choose) (convert)

                            ∨                      

                        ≤ or ≥  

the answer would be a
