Both Jacques Charles and Joseph Louis Guy-Lussac were avid balloonists. In his original flight in 1783, Jacques Charles used a balloon that contained approximately 31,150 L of H2. He generated the H2 using the reaction between iron and hydrochloric acid:
Fe(s) + 2 HCl(aq) → FeCl2(aq) + H2(g)
How many kilograms of iron were needed to produce this volume of H2 if the temperature was 22 °C?
