In a given situation, 42.094 g/mol of calcium hydride reacts with water to form hydrogen gas in relevance to the equation: CaH₂(s) + 2H₂O(l)→ Ca(OH)2(aq) + 2H₂(g) A laboratory researcher experimented 225 mL of wet H2 with 2.016 g/mol that is collected in water with 18.015 g/mol at 298 K and 748 barometric pressure and the given vapor pressure of water at 298 K is at 26.74 torr. Find the partial pressure in atm of hydrogen in the experiment. Find the grams of calcium hydride consumed in the experiment.
