Water can be from the stoichiometric hydrogen with oxyger many grams of H20 generated when 45.3 gO 2 reacts with excess hydrogen?

The total grams of H2O generated is 48.159 grams

Explanation:

45.3g of O2 is 1.415 moles.

The molar ratio between O2 and H2 to form H2O is 1:2 as the balanced equations indicates: 2H2 + O2--> 2H2O

Therefore, the moles for hydrogen is 1.415*2 = 2.813

Then, we multiply the moles by the molar mass to get the Mass of Hydrogen: 2.813*1.01=2.859.

Finally we add the weight of 2H2 and O2: 2.869 + 45.3= 48.159g
