Answer:
99.7 g Fe
Step-by-step explanation:
a) Write the balanced chemical equation
Fe2O3 + 3CO → 2Fe + 3CO2
b) Convert grams CO to moles CO
Moles CO = 75.0 g CO x (1 mol CO/28.01 g CO) = 2.678 mol CO
c) Use the molar ratio of Fe:CO to convert moles of CO to moles of Fe
2.678 mol CO x (2 mol Fe/3 mol CO) = 1.785 mol Fe
d) Convert moles of Fe to grams of Fe
1.785 mol Fe x (55.84 g Fe/1 mol Fe) = 99.7 g Fe
