One hundred grams of iron oxide (FeO) is reacted with 1000 cm³ of pure hydrogen(STP) in a closed system at one atmosphere using a temperature of 400 oC for an extended time. What is the weight of the pure Fe that would be formed? Assume that FeO is stable at 400 ^oC (W_H2 = 2 gm/mol; W_Fe =56 gm/mole)
