Answer:
41.51 g of CO
Explanation:
The balance chemical equation for given double displacement reaction is,
Fe₂O₃ + 3 CO → 2 Fe + 3 CO₂
Step 1: Calculate moles of Fe₂O₃:
Moles = Mass / M.Mass
Moles = 78.9 g / 159.68 g/mol
Moles = 0.494 moles
Step 2: Calculate moles of CO:
According to equation,
1 mole of Fe₂O₃ reacted with = 3 moles of CO
so,
0.494 moles of Fe₂O₃ will react with = X moles of CO
Solving for X,
X = 0.494 mol × 3 mol ÷ 1 mol
X = 1.482 moles of CO
Step 3: Calculate Mass of CO as:
Mass = Moles × M.Mass
Mass = 1.482 mol × 28.01 g/mol
Mass = 41.51 g of CO
