Metal hydrides react with water to form hydrogen gas and metal hydroxide. For example, SrH2(s)+2H2O(l)Sr(OH)2(s)+2H2(g) You wish to calculate the mass of hydrogen gas that can be prepared from 7.73g of SrH2 and 6.44g of H2O. Part 1 of 4 How many moles of H2 can be produced from the given mass of SrH2 ? Round your answer to 3 significant figures. moles Part 2 of 4 How many moles of H2 can be produced from the given mass of H2O ? Round your answer to 3 significant figures
