Calculate the percent yield of iron if 950 g of Fe3O4 underwent the reaction shown in the chemical equation below and 533 g of Fe was isolated from the reaction mixture. Fe3O4 (s) + 2 C(s) ----> 2 CO2 (g) + 3 Fe(s)

1). 25.9%

2). 77.5%

3). 56.1%

4). None of the above.

Based on my calculations, the answer came out to be number 2. I used the formula %yeild = actual yield/theorical yield * 100

You are correct. I found 687.4 g for the theoretical yield.
