Answer:

3.4 x 10²⁵ atoms Ag

Step-by-step explanation:

To find the amount of silver (Ag) atoms, you need to use Avogadro's number to convert between moles and atoms. Make sure to arrange the ratio in a way that allows for the cancellation of moles. The final answer should have 2 sig figs to correlate with the number of sig figs in the given value (56 = 2 sig figs).

Avogadro's number:

6.022 x 10²³ atoms = 1 mole

56 moles Ag 6.022 x 10²³ atoms
-------------------- x ---------------------------------- = 3.4 x 10²⁵ atoms Ag
1 mole
