Answer:

7.64 Moles

Step-by-step 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
