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 %
