Two moles of oxygen gas is reacted with hydrogen gas to produce water in this reaction: 2 h2 + o2 → 2 h2o in the lab you actually made 33.1 grams of water. what is the percent yield? 218.10% 91.80% 45.87% 54.50%

Answer : The percent yield of is, 45.97 %

Explanation :

First we have to calculate the moles of water.

The balanced chemical reaction is,

From the balanced reaction, we conclude that

As, 1 moles of react to give 2 moles of

So, 2 moles of react to give moles of

Now we have to calculate the mass of .

The mass water produces, 72 g

Now we have to calculate the percent yield of .

Therefore, the percent yield of is, 45.97 %
