Answer 2

Answer:

247 grams NaCl

Explanation:

We want to convert 4.23 moles of NaCl into grams. To do so, we must first find the molar mass of NaCl.

According to the periodic table, it is 22.99 + 35.45 = 58.44 g/mol.

Now we must multiply the number of moles (4.23) by the molar mass to get the mass of NaCl:

4.23 mol * 58.44 g/mol ≈ 247 g

Thus, the answer is 247 grams of NaCl.
