3.) One method used in the eighteen century to generate hydrogen was to pass steam through red-hot steel tubes. The following reaction takes place:
3Fe(s)+4H20(g)--->Fe3O4(s)+4H2(g)

1. What volume of hydrogen at STP can be produced by the reaction of 6.28 g of iron?

2. What mass of iraon will react with 500.0 L of steam at 25 degrees C and 1.00 atm pressure?

3. If 285g of Fe3O4 are formed, what volume of hydrogen, measured at 20 degrees C and 1.06 atm, is produced?

(Im new to chemistry please help)
