Explanation:

Step1: Identify total weight and percentage

The total weight of the bar is 7.5 ounces, and the percentage of iron is 9% (or 0.09 in decimal form).

Step2: Calculate iron weight

To find the weight of iron, multiply the total weight by the percentage of iron. So, we calculate \( 7.5\times0.09 \).
\( 7.5\times0.09 = 0.675 \)

Answer:

0.675 ounces
