Understanding the Problem

When faced with a complex calculation, it's essential to choose the correct setup to ensure accuracy and efficiency. In this article, we'll explore a specific calculation involving the conversion of aluminum (Al) to iron (Fe) and discuss the correct setup for this process.

The Calculation

Let's examine the given calculation:

A. $0.0257 \, \text{g Al} \times \frac{26.98 \, \text{g Al}}{1 \, \text{mol Al}} \times \frac{2 \, \text{mol Al}}{2 \, \text{mol Fe}} \times \frac{55.85 \, \text{g Fe}}{1 \, \text{mol Fe}}$

This calculation involves the conversion of aluminum to iron, and we need to determine the correct setup for this process.

Analyzing the Setup

To analyze the setup, let's break down the calculation into its individual components:

Conversion of aluminum to moles: The first step involves converting the given mass of aluminum (0.0257 g) to moles using the molar mass of aluminum (26.98 g/mol).
Conversion of moles to moles: The second step involves converting the moles of aluminum to moles of iron using the given ratio of 2 mol Al to 2 mol Fe.
Conversion of moles to mass: The final step involves converting the moles of iron to mass using the molar mass of iron (55.85 g/mol).

Identifying the Correct Setup

Upon analyzing the setup, we can identify the following issues:

The conversion of moles of aluminum to moles of iron is incorrect, as it assumes a 1:1 ratio between the two elements.
The conversion of moles of iron to mass is also incorrect, as it uses the molar mass of iron without considering the given mass of aluminum.

Correct Setup

To correct the setup, we need to re-evaluate the calculation and ensure that the conversions are accurate and consistent. Here's the corrected setup:

B. $0.0257 \, \text{g Al} \times \frac{1 \, \text{mol Al}}{26.98 \, \text{g Al}} \times \frac{2 \, \text{mol Fe}}{2 \, \text{mol Al}} \times \frac{55.85 \, \text{g Fe}}{1 \, \text{mol Fe}}$

In this corrected setup, we've:

Corrected the conversion of moles of aluminum to moles of iron to reflect the correct ratio.
Corrected the conversion of moles of iron to mass to use the correct molar mass of iron.

Conclusion

In conclusion, selecting the correct setup for a calculation is crucial to ensure accuracy and efficiency. By analyzing the given calculation and identifying the issues, we were able to correct the setup and provide a revised calculation that accurately reflects the conversion of aluminum to iron.
