Question

Find the number of moles if you have 1.2 x 1048 copper atoms.

Answer 1

1.993 × 10^(24) moles

Step-by-step explanation:

From avogadro's number, we have that;

1 mole of atoms contain 6.022 × 10^(23) atoms

Therefore, 1.2 x 10^(48) atoms of copper will contain;

(1.2 x 10^(48) × 1)/(6.022 × 10^(23)) = 1.993 × 10^(24) moles
