Balloon Iron
Chemistry Help?
Here's the problem:
In 1897 the Swedish explorer Andree tied 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 m^3 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 0C (273K), a pressure of 1.0 atm during filling, and 100% yield.
Steps to show this would be wonderful!
We need to calculate how many moles of H2 there are. Use the ideal gas law.
V = 4800 m^3 x (10 dm / m)^3 = 4.8 x 10^6 dm^3 = 4.8 x 10^6 L
PV = nRT
n = PV / RT = (1.0)(4.8 x 10^6) / (0.0821)(273)
= 214,000 moles H2
If you lose 20% during filling, then you really need
1.2 x 214,000 moles = 257,000 moles H2.
257,000 moles H2 x (1 mole Fe / 1 mole H2) x (55.85 g Fe / 1 mole Fe) = 1.43 x 10^7 g Fe = 14,300 kg Fe.
257,000 moles H2 x (1 mole H2SO4 / 1 mole H2) x (98.1 g H2SO4 / 1 mole H2SO4) x (100% / 98%) = 2.57 x 10^7 g H2SO4 = 25,700 kg H2SO4.

Two Balloon Iron Man
Gas Laws interesting question but difficult. Help will be much appreciated.?
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 4350 m3 and the loss of hydrogen gas during filling was estimated at 20.0%. What mass (in kg) of iron splints and 86.2% (by mass) H2SO4 were needed to ensure the complete filling of the balloon? Assume a temperature of 0°C, a pressure of 1.00 atm during filling, and 100% yield.
iron splints:_________ kg
86.2% sulfuric acid: ___________kg
1mol H2 at STP ( you are happily working at STP) has a volume of 22.4 litres.
You need 4350m³ , therefore you will need:
4350000/22.4 = 194,196.4mol H2
But you lost 20% of the gas, therefore you will need to produce:
Mol of H2 = 100/80*194,196 = 242,746mol H2
From the balanced equation:
1mol Fe will produce 1mol H2
You require 242,746 mol Fe
Molar mass Fe = 55.847g/mol
Mass of Fe required: 242,746*55.847 = 13,556,610g Fe
You require 13,557 kg of Fe
Similarly, from the balanced equation:
1mol H2SO4 will produce 1mol H2
You require 242,746 mol H2SO4
Molar mass H2SO4 = 98.0791 g/mol
242,746mol = 242,746*98.0791 = 23,808,309g H2SO4 100%
But your acid is 86.2% : you then need
23,808,309*100/86.2 = 27,619,848g
You require: 27,620kg H2SO4 solution.
