Metal hydrides react with water to form hydrogen gas and the metal hydroxide. For example,
SrH₂(s) + 2H₂O(l) → Sr(OH₂)(s) + 2H₂(g)
You wish to calculate the mass (g) of hydrogen gas that can be prepared from 5.70 g of SrH₂ and 4.75 g of H₂O.
(a) What amount (mol) of H₂ can be produced from the given mass of SrH₂?
