Question

In 1897 the Swedish explorer Andreé tried to reach the North Pole in a balloon. The balloon was filled with hydrogen gas. The hydrogen gas was prepared from iron splints and diluted sulfuric acid. The reaction is
Fe(s) + H2SO4(aq) → FeSO4(aq) + H2(g)
The volume of the balloon was 4800 m3, and the loss of hydrogen gas during filling was estimated at 20%. What mass of iron splints and 98% (by mass) H2SO4 were needed to ensure the complete filling of the balloon? Assume a temperature at 0oC, a pressure of 1.0 atm during filling, and 100% yield.
