Answer:
3.03 x 10²³ formula units
Explanation:
First we convert 48.0 grams of magnesium chloride into moles, using its molar mass:
- 48.0 g ÷ 95.21 g/mol = 0.504 mol MgCl₂
Then we convert 0.504 moles into formula units, using Avogadro's number:
- 0.504 mol * 6.023x10²³ formula units/mol = 3.03x10²³ formula units
