How many moles of aluminum do 4.60×10^24 aluminum atoms represent? express your answer using three significant figures.

              7.64 Moles

Explanation:

                      As we know one mole of any substance contains 6.022 × 10²³ particles (atoms, ions, molecules or formula units). This number is also called as Avogadro's Number.

The relation between Moles, Number of Particles and Avogadro's Number is given as,

                          Number of Moles  =  Number of Particles ÷ 6.022 × 10²³

Putting values,

                          Number of Moles  =  4.60 × 10²⁴ Particles ÷ 6.022 × 10²³

                         Number of Moles  =  7.64 Moles

the answer is the
