83.3% yield

Explanation:

First, we need to convert 240 g of into moles:

Next, find the theoretical Fe yield using molar ratios.

Then convert this back into grams:

Note that actual yield is only 140 g Fe so percentage yield is

%= 83.3%

pie chart because it is in percents ( % )

there is none because earth is stationary and flat.
