How to calculate the mass of carbon needed to produce 1 mole of iron from iron oxide using the given array?
a. (1 mole of FeO)(56 g/mol FeO)(1 mol C/1 mol FeO)(12 g/mol C)
b. (1 mole of FeO)(72 g/mol FeO)(1 mol C/1 mol FeO)(12 g/mol C)
c. (1 mole of FeO)(56 g/mol FeO)(2 mol C/2 mol FeO)(12 g/mol C)
d. (1 mole of FeO)(72 g/mol FeO)(2 mol C/2 mol FeO)(12 g/mol C)
