To find the number of moles of carbon needed to completely reduce 2154 grams of black iron oxide (FeO), we first need to calculate the molar mass of FeO. The molar mass of FeO is 71.85 g/mol. Next, we need to convert the mass of FeO to moles by dividing the given mass by the molar mass. Therefore, 2154 grams of FeO is equal to 29.95 moles. Since the balanced chemical equation for the reduction of FeO by carbon is FeO + C → Fe + CO, we can see that 1 mole of FeO requires 1 mole of carbon. Therefore, 29.95 moles of carbon are needed to completely reduce 2154 grams of FeO. **
