Answer 1

Hello Dear.

Here is the answer---

→→→→→→→→→

Number of Moles of FeO₂ = 3.5 moles.
Molecular Mass of FeO₂ = 88 grams/moles.

Using the Formula,

No. of Molecules = No. of Moles × Avogadro's Number.
                            = 3.5 × 6.022 × 10²³
                            = 21.077 × 10²³ molecules.

Thus, the Number of Molecules in 3.5 mole of FeO₂ is 21.077 × 10²³.
