Final answer:
The number of formula units in a 6.07 mol sample of FeCl₃ is approximately 3.65 × 10²⁴, found by multiplying the moles by Avogadro's number (6.022 × 10²³ units/mol).
Step-by-step explanation:
The question is asking about the number of formula units in a 6.07 mol sample of ferric chloride, FeCl₃. To find the number of formula units, we can use Avogadro's number, which states that there are 6.022 × 10²³ formula units in one mole of a substance.
To find the total number of formula units in 6.07 moles, we simply multiply the number of moles by Avogadro's number:
Number of formula units = 6.07 mol × 6.022 × 10²³ units/mol
This mathematical operation yields approximately 3.65 × 10²⁴ formula units in a 6.07 mol sample of FeCl₃.
