hydrogen gas (h2) reacts with oxygen gas (o2) to form water (h2o). what mass of water can be produced by the reaction of 50.0 g o2 in excess hydrogen gas?
Explanation:25 moles of hydrogen 50.0g can react with 12.5 moles of oxygen (12.5x32g). so oxygen is limiting reagent, reaction proceed accordingly. 50.0g of oxygen can produce =(50 x 36)/36 = 56.25g
