What is the mass of 8 moles of sodium chloride?

To find the mass of 8 moles of sodium chloride (NaCl), first determine its molar mass. Sodium has a molar mass of approximately 23 g/mol, and chlorine has a molar mass of about 35.5 g/mol, giving NaCl a total molar mass of about 58.5 g/mol. Therefore, the mass of 8 moles of NaCl is calculated as 8 moles × 58.5 g/mol = 468 grams.
