Answer to Question #346581 in General Chemistry for Han

Question

In this unbalaced chemical reaction.

Fe3O4 + H2O --------> Fe + H2O

How many grams of H2O will be produced, if 41.95g of Fe3O4 are reacted completely with hydrogen? Show the solution.

Answer 1

Fe₃O₄ + 4H₂ -------->3Fe + 4H₂O

m(H₂O) = (m( Fe₃O₄) * 4Mr(H₂O)) / Mr(Fe₃O₄)

m(H₂O) = (41.95 g * 4 * 18 g/mol) / 231.5 g/mol = 13.05 g
