This question sounds like it is a second part of a 2 part question, where the first part of the question results in a volume of hydrogen gas being produced.
Using PV = nRT you should be able to take the answer from part i and input it to solve for this part of the ...
This solution uses the ideal gas concept to determine the volume of the hydrogen generated at depth of the Titanic with a temperature of -1 degrees Celsius. All workings and formulas are shown.
Hydrogen Gas Problem Using the Ideal Gas Law
Consider a vehicle powered by hydrogen gas.
a. About 3.1 kg of H2 is required for a vehicle to have a 500 km range. Assume ideal gas behavior and a storage tank of 60 L (a comparable size to conventional gasoline vehicles). What tank pressure atm might one expect at 25 degrees celsius?
b. Since their discovery in 1991, tiny graphite-like cylinders known as nanotubes have been widely researched. These nanotubes (1-3 nm in diameter) have high tensile strength, high electrical conductivity, and a high surface area. Hydrogen can readily abosrb onto these carbon fibers. The textbook indicates that these nanotubes can absorb three times their weight in H2. What minimum amount of this carbon allotrope (g) would be needed to reduce the tank pressure in the above hydrogen-powered vehicle to 20.0 atm?View Full Posting Details
