Can anyone help me with Organic Lab Question?

[Aideney]

Have to hang it in on Wed so I am really appreciate if anyone can tell me how to answer them.


We dissolve sucrose in water and have 250 mL. We put 25.0 ml of sucrose into each beaker, and there are 7 of them. solution #0 is in room temp and no HCl, the other 6 are in hot water and has HCl and converted to fructose and glucose.

Qs: Finding the initial mass of sucrose in each of the solution. Suppose you are asked to produce a mixture of three sugars where 67% sucrose has been converted, at what point should the reaction be stopped?

This is my data: 
Mass of sucrose: 50.094g 
Time & Temp:
 5 mins = 65.1 
10 = 63.5 
15 = 63.5
20 = 63.2 
25 = 63.2 
30 = 63.2
