We’re being asked to determine how many grams of water vapor are formed assuming it is the only product in the reaction of 1.90 g of hydrogen, H2 and 15.2 g of Oxygen, O2.


Recall that the Law of Conservation of mass states that matter cannot be created or destroyed.  


This means that the amount of reactants will be the same amount of the products.
