Jacques Charles used this reaction to prepare hydrogen gas for his historic balloon flights: Fe(s) + H2SO4(aq) = FeSO4(aq) + H2(g) He wants to prepare a small test balloon to check flight conditions before he lifts off in his giant balloon. He has 234 grams of iron and 382 mL of 12 M (mol / L) sulfuric acid available. What is the maximum size his test balloon can be in L? The temperature in Paris is a chilly 18 celsius and the atmospheric pressure if 770 mm Hg. (This is a limiting reactant problem).
