Answer:
a)82.5 g
Explanation:
To solve this problem we will use Avogadro's number, which states the number of formula units per mole.
- 8.50x10²³formula units ÷ 6.023x10²³ formula units/mol = 1.41 mol
Then we convert 1.41 moles of NaCl to grams, using its molar mass:
- 1.41 mol NaCl * 58.44 g/mol = 82.4 g
The closest answer is option a).
