Answer:
1.06x10²² formula units
Explanation:
First we convert 5.164 g of CaI₂ into moles, using its molar mass:
- 5.164 g ÷ 293.887 g/mol = 0.0176 mol
Then we convert 0.0176 moles into formula units, using Avogadro's number, which relates the number of formula units present in 1 mol:
- 0.0176 mol * 6.023x10²³ FormulaUnits/mol = 1.06x10²² formula units
