Answer:
Approximately .
Explanation:
The actual yield of was given. The theoretical yield needs to be calculated from the quantity of the reactant.
Balance the equation for the hydrolysis of water:
.
Note the ratio between the coefficient of and

:
.
Make use of the ratio to find the theoretical yield of
(in terms of number of moles of molecules.)
.
Calculate the mass of that approximately of
(theoretical yield.)
.
That would correspond to the theoretical yield of (in term of the mass of the product.)
Given that the actual yield is , calculate the percentage yield:
