For this problem we use the Avogadro's number which is an empirical value that relates the number of particles to the number of moles. Its approximated value is 6.022*10²³ atoms/mole. The solution is as follows:

4.40*10²⁴ aluminum atoms * 1 moles/6.022*10²³ atoms = 7.306

Thus, there are 7.306 moles of aluminum.
