Answer : 37 drops are delivered per milliliter of the solution.
Explanation :
The problem gives us lot of extra information.
We want to find the number of drops delivered in 1 milliliter here.
We have been given that, one drop of the solution delivers 0.027 mL of solution.
Let us use this as a conversion factor, 
Let us find number of drops in 1 mL using this conversion factor.

Therefore we can say that 37 drops are delivered per milliliter of the solution.
(35/18.02)(6.02kJ)=11.6926 kiloJoules
