You are given a correctly balanced equation: C6H12O5 + 6O2 ==> 6CO2 + 6H2O
However, the question is not valid for several reasons. First, it asks how many grams of sucrose are required, when sucrose is not even involved in this chemical reaction. Sucrose has the formula C12H22O11 and what this reaction uses is glucose, C6H12O6. While it is true that sucrose can be broken down to produce glucose, I doubt that this was the intent of the question.
Second problem is that water doesn't have a varying molarity, especially in introductory chemistry. It is 55.5 M, so to produce 345.7 ml of 4.36 M H2O doesn't seem correct.
