One of the problems with using hydrogen gas as a fuel to power cars is that it must be stored in high pressure tanks. The high pressure tanks that would be required to take a car a reasonable distances between refuelling stops are often far too large for the average vehicle. What would be the necessary internal volume of a tank that stored hydrogen at 20.0 atm, if you needed to store enough hydrogen to react with 1435 g of oxygen gas at 32oC according to the chemical equation below? 2 H2(g) + O2(g) H2O(g)
