Question 10

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

Calculate the number of $[Mo7O24]6−[\text{Mo}_7\text{O}_{24}]^{6-}$ ions that can be formed from a sample containing $0.35$ moles of molybdenum ( $Mo\text{Mo}$ ) atoms.

The Avogadro constant $\times 10^{23}\text{ per mole}$ .
