Answer: 1.66 x10+24 atoms of Al
Explanation: to find the number of atoms we use the relationship of moles and avogadro's number which is constant ( 6.022x 10+23) atoms or molecules as its units.
solution:
2.75 moles Al x 6.022x10 +23 / 1 mole Al = 1.66x10+24 atoms of Al
Answer:
Explanation:
1 mole = 6.022×10∧23 atoms
2.75 Mole = x
Hence, 2.75 * 6.022×10∧23 = 16.56 * 10∧23 atoms
