How many moles of aluminum do 2.66×10^24 aluminum atoms constitute?
well, what's
2.66*10^24 / 6.023*10^23 ?
To determine the number of moles of aluminum, you need to use Avogadro's number, which states that one mole of any substance contains 6.022 × 10^23 particles (atoms, molecules, or ions).
In this case, you have 2.66 × 10^24 aluminum atoms. To find the number of moles, divide the number of atoms by Avogadro's number.
moles of aluminum = (number of aluminum atoms) / (Avogadro's number)
moles of aluminum = (2.66 × 10^24) / (6.022 × 10^23)
moles of aluminum ≈ 4.42
Therefore, 2.66 × 10^24 aluminum atoms constitute approximately 4.42 moles of aluminum.
