How many grams of water, H₂O, can be produced from the reaction of 25.0 grams of hydrogen, H₂, and 225 grams of oxygen, O₂? A)250 grams B)225 grams C)200 grams D)25 grams

Question

Quizplus · Accepted Answer

The balanced equation for the reaction is: 
2H2 + O2 -> 2H2O 
Using stoichiometry, we can calculate the amount of water produced: 
25.0 g H2 x (1 mol H2 / 2.016 g H2) x (2 mol H2O / 2 mol H2) x (18.015 g H2O / 1 mol H2O) = 281.9 g H2O 
225 g O2 x (1 mol O2 / 32.00 g O2) x (2 mol H2O / 1 mol O2) x (18.015 g H2O / 1 mol H2O) = 506.5 g H2O 
The limiting reagent is hydrogen, which produces 281.9 g of water. Therefore, the maximum amount of water that can be produced is 281.9 g. So, the closest answer choice is B (225 grams).
