Question
In 1897 the Swedish explorer Andrée 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

\[ \text{Fe(s)} + \text{H}_2\text{SO}_4\text{(aq)} \rightarrow \text{FeSO}_4\text{(aq)} + \text{H}_2\text{(g)} \]

The volume of the balloon was 4800 m³ and the loss of hydrogen gas during filling was estimated at 10%. What mass of iron splints and 98% (by mass) \(\text{H}_2\text{SO}_4\) 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 \(\text{Fe} = \_\_\_\_\_\_\_\_ \text{g}\)
- Mass of \(\text{H}_2\text{SO}_4 = \_\_\_\_\_\_\_\_ \text{g}\)
