Answer:
2100g or 2.1kg
Explanation:
Based on the equation given,
One mole of Fe2O3 gives two moles of Fe
Molar mass for Fe2O3 is 160g/mol
Molar mass for two Fe is 112g/mol
Convert 3kg to gram
3×1000=3000grams
160g of Fe2O3-112 g of Fe
3000g of Fe2O3-xg of Fe
Xg=3000×112/160
Xg=2100g
To convert to kg
2100/1000=2.1kg
Mass of Fe is 2.1kg
I would go with C, because you would always start with products and end with reactants.
