We are asked how many kilograms of iron were needed to produce this volume of H2 if the temperature was 24 oC.
Calculate moles H2:
P = 1.00 atm
T = 24 oC +273.15 = 297.15 K
V = 31200 L
R= 0.08206 L-atm/mol-K
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 31200 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 24 oC? (For simplicity, assume that the pressure experienced by the balloon will be 1.00 atm.)
