Answer: (D)

Verified step by step guidance

1. Identify the given quantity and what is asked: You have 5.00 moles of sodium chloride (NaCl) and need to find the mass in grams.
2. Determine 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.
3. Calculate the molar mass of NaCl using the formula: \(\text{Molar mass of NaCl} = 22.99 + 35.45\) g/mol.
4. Use the relationship between moles, molar mass, and mass: \(\text{Mass} = \text{Moles} \times \text{Molar mass}\).
5. Substitute the values into the formula: \(\text{Mass} = 5.00 \text{ mol} \times \text{Molar mass of NaCl (g/mol)}\) to find the mass in grams.
