Here's how to calculate the grams of sodium chloride (NaCl) in 8 moles:

1. Find the molar mass of NaCl:

* Sodium (Na) has a molar mass of 22.99 g/mol

* Chlorine (Cl) has a molar mass of 35.45 g/mol

* Molar mass of NaCl = 22.99 g/mol + 35.45 g/mol = 58.44 g/mol

2. Use the formula:

* Grams = Moles x Molar mass

3. Calculate:

* Grams = 8 moles x 58.44 g/mol = 467.52 grams

Therefore, 8 moles of sodium chloride (NaCl) is equal to 467.52 grams.
