Calcium hydride reacts with water to produce hydrogen gas according to the following reaction: CaH2(s) + 2 H2O(l) ----> 2H2(g) + Ca(OH)2(aq) This reaction is used to generate hydrogen gas to inflate air bags in cars and life rafts on boats and for similar uses where a simple compact means of hydrogen generation is necessary. Assuming complete reaction with water, how many grams of calcium hydride are required to fill a raft to a total pressure of 2.0 atm at 25oC if the volume of the raft is 1,000 L?
