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 4400 m3 and the loss of hydrogen gas during filling was estimated at 10.%. 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. Mass of Fe = ______g Mass of H2SO4= ______g

The volume of the balloon was 4400 m3 and the loss of hydrogen gas during filling was estimated at 10.%. 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.
Mass of Fe = ______g
Mass of H2SO4= ______g
The balanced reaction taking place is given as,
=> Fe (s) + H2SO4 (aq) ------> FeSO4 (aq) + H2 (g)
Given : Volume of balloon (i.e container of gas) = 4400 m3 = 4.4 X 106 L (since 1 m3 = 1000 L)
Temperature = 0.0 oC
Pressure = 1.0 atm
And loss in mass of gas during filling = 10 %
