How many grams of rust form when 453 kJ of energy are released?

1 answer

Write the equation and balance it.
Then look up the energy released when 1 mole of rust forms and calculate molar mass of that many grams.
g rust formed = grams rust from the equation x (453,000/DHrxn). It's tough to write this to make sense. If you will supply the equation the the delta H for the reaction, I can be a little more specific.
