A balloon is filled with hydrogen gas and produces the following chemical reaction between iron and sulfuric acid: Fe(s) + H2SO4(aq) --> FeSO4 (aq) + H2(g). The total mass that can be lifted by a balloon is equal to the difference between the mass of gas in the balloon and the mass of air displaced by the balloon. How much mass could be lifted by the balloon stated above? What if the same balloon was filled with helium instead?
