Final answer:
To determine the number of moles in 5.52 × 10²³ formula units of Cabr₂, we can use Avogadro's number and the conversion factor from formula units to moles.
Step-by-step explanation:
To determine the number of moles in 5.52 × 10²³ formula units of Cabr₂, we need to use Avogadro's number. Avogadro's number is the number of particles (atoms, ions, or molecules) in one mole of substance, which is approximately 6.022 × 10²³. We can use this conversion factor to find the number of moles.
Step 1: Convert the number of formula units to moles.
5.52 × 10²³ formula units × (1 mole / 6.022 × 10²³ formula units) = 0.917 moles
Therefore, there are approximately 0.917 moles in 5.52 × 10²³ formula units of Cabr₂.
