The equation for one of the reactions in the process of turning iron ore into the metal is

Fe2O3 (s) + 3CO2 (g) → 2Fe (s) + 3CO2 (g)

If you start with 3.00 kg of each reactant, what is the maximum mass of iron you can produce?

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
