Question

For the reaction 2Fe + O2 > 2FeO, how many grams of iron oxide are produced from 5.00 moles of iron?

Answer 1

Answer:

359 grams FeO

Explanation:

To find how many grams FeO are produced, you need to use the moles of Fe, convert it to moles of FeO (using the mole-to-mole ratio from the equation), then convert the moles of FeO to grams (using the molar mass from the periodic table).

2 Fe + O₂ --> 2 FeO

Molar Mass (FeO) = 55.845 g/mol + 16.00 g/mol

Molar Mass (FeO) = 71.845 g/mol

5.00 moles Fe           2 moles FeO            71.845 grams

                                   2 moles Fe               1 mole FeO
