• A. 65.4 g
• B. 229 g
• C. 114 g
• D. 3.50 g

Answer: (B)

Verified step by step guidance

1. Identify the given quantity: 3.50 moles of Zn atoms.
2. Recall that the molar mass of zinc (Zn) is approximately 65.4 g/mol. This value represents the mass of one mole of Zn atoms.
3. Use the formula to convert moles to mass: \(\text{mass} = \text{moles} \times \text{molar mass}\).
4. Substitute the known values into the formula: \(\text{mass} = 3.50\ \text{mol} \times 65.4\ \text{g/mol}\).
5. Multiply the numbers to find the mass of 3.50 moles of Zn atoms (do not calculate the final value here, just set up the expression).
