Question

Calculate the number of atoms in 3 moles of carbon atoms​

Answer 1

1,806,000,000,000,000,000,000,000 atoms.

Step-by-step explanation:

1 mol of anything is 6.022*10^23 units

1 mol carbon atoms = 6.022*10^23 carbon atoms

3 mol carbon atoms = 3*6.022*10^23 = 1.8*10^24 atoms

Correctly - your answer should have only 1 significant digit: 2 * 10^24 atoms.
