Final answer:
The statement is false; while 1 mol of Fe2O3 does contain 3.011 × 10^24 atoms due to having 5 atoms per molecule, it inaccurately conveys the definition of a mole according to Avogadro's number.
Step-by-step explanation:
The statement '1 mol of Fe2O3 molecules contains 3.011 × 1024 atoms.' is false. A mole of any substance, according to Avogadro's number, contains 6.022 × 1023 representative particles. In the case of Fe2O3, which is iron (III) oxide, each molecule consists of 5 atoms (2 iron and 3 oxygen atoms).
Therefore, 1 mol of Fe2O3 would contain 5 × 6.022 × 1023 atoms, which equals 3.011 × 1024 atoms, so the statement is mathematically correct but it does not conform with the standard definition of a mole.
