Question

Fe3O4(s) + C(s) > CO2 + Fe
Balance the chemical reaction and calculate how many moles of Fe3O4 must be reacted to produce 440 gr CO2 (the > is an arrow)
Fe3O4(s) + 2C(s) > 2CO2 + 3Fe

mols CO2 = grams/molar mass = ?

Using the coefficients in the balanced equation, convert mols CO2 to mols Fe3O4.
