Heptamolybdate ions, [Mo7O24]6−[\text{Mo}_7\text{O}_{24}]^{6-}[Mo7​O24​]6−, are large polyoxometalate clusters used in industrial catalysis.

Calculate the number of [Mo7O24]6−[\text{Mo}_7\text{O}_{24}]^{6-}[Mo7​O24​]6− ions that can be formed from a sample containing 0.350.350.35 moles of molybdenum (Mo\text{Mo}Mo) atoms.

The Avogadro constant =6.02×1023 per mole= 6.02 \times 10^{23}\text{ per mole}=6.02×1023 per mole.
