Calcium hydride, CaH2, reacts with water to form hydrogen gas. CaH2(s) + 2 H2O(l) Ca(OH)2(aq) + 2 H2(g) This reaction is sometimes used to inflate life rafts, weather balloons, and the like, where a simple, compact means of generating H2 is desired. How many grams of CaH2 are needed to generate 13.0 L of H2 gas if the pressure of H2 is 740. torr

Calcium hydride (CaH2) reacts vigorously with water according to the unbalanced equation shown: CaH2 (s) + H2O (1) --> Ca(OH)2 (s) + H2 (g) Determine the moles of H2 that could be produced if 24.6 g of calcium hydride were to undergo the reaction above. Enter a numerical value in the correct number of significant figures; do not enter units.
