#49 In 1897 the Swedish explorer
Andree 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 given below.
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 of 0°C, a pressure of 1.0 atm during
filling, and 100% yield.
