Lithium hydride reacts with water as follows.
LiH(s) + H2O(l) -->LiOH(aq) + H2(g)

During World War II, U.S. pilots carried LiH tablets. In the event of a crash landing at sea, the LiH would react with the seawater and fill their life belts and lifeboats with hydrogen gas. How many grams of LiH are needed to fill a 3.6 L life belt with hydrogen gas at 1.04 atm and 27.7°C?
