5. How many grams of iron oxide can be produced from 2.50 g of oxygen reacting with iron, according to the following equation?
2 Fe (s) + 3 O2 (g) -->2 Fe2O3(s)
Answered by Scott
the molar mass of O₂ is 32 g

3 moles of oxygen produce 2 moles of iron oxide

(2.50 / 32)* 2/3 = moles of Fe₂O₃

the molar mass of Fe₂O₃ is 159.7 g
Answered by Marley
88 g
