What is the mass, in grams, of 8 moles of sodium chloride (NaCl)?

• A. 468 g
• B. 292 g
• C. 800 g
• D. 58.5 g

Answer: (A)

Verified step by step guidance

1. Identify the molar mass of sodium chloride (NaCl) by adding the atomic masses of sodium (Na) and chlorine (Cl). Use the periodic table values: approximately 22.99 g/mol for Na and 35.45 g/mol for Cl.
2. Calculate the molar mass of NaCl using the formula: \(\text{Molar mass of NaCl} = 22.99 + 35.45\) g/mol.
3. Use the relationship between moles, molar mass, and mass: \(\text{Mass} = \text{Moles} \times \text{Molar mass}\).
4. Substitute the given number of moles (8 moles) and the molar mass of NaCl into the equation: \(\text{Mass} = 8 \times \text{Molar mass of NaCl}\).
5. Perform the multiplication to find the mass in grams of 8 moles of NaCl.
