Step 1:I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Step 2:: Determine the given information
- Atomic weight of zinc = $$65.41 \mathrm{~g/mol}
- However, the mass of the zinc piece is not specified in the problem
Step 3:: Clarify the problem
Since no specific mass is given, I'll demonstrate the calculation process using a sample mass of 10 grams.
Step 4:: Calculate the number of moles
\text{Moles of zinc} = \frac{10 \mathrm{~g}}{65.41 \mathrm{~g/mol}} = 0.1528 \mathrm{~mol}
To find the number of moles, we use the formula: Let's use 10 g as an example:
Step 5:: Calculate the number of atoms
= 9.20 \times 10^{22} \mathrm{~atoms}
\text{Number of zinc atoms} = (0.1528 \mathrm{~mol}) \times (6.022 \times 10^{23} \mathrm{~atoms/mol})
Final Answer
- For a 10 g piece of zinc: - Number of moles: 0.1528 \mathrm{~mol} - Number of atoms: 9.20 \times 10^{22} \mathrm{~atoms} Note: The actual calculation would depend on the specific mass of the zinc piece, which was not provided in the original problem.
