Answer:
3.4 x 10²⁵ atoms Ag
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
