To find the mass of C12H22O11 in the final solution, we can use the principle of conservation of mass:

m1(розч) = m2(розч) + m(C12H22O11)
200g = 100g + m(C12H22O11)
m(C12H22O11) = 200g - 100g
m(C12H22O11) = 100g

Now, we can calculate the final weight percent of C12H22O11 in the solution:

w3(C12H22O11) = (m(C12H22O11) / m2(розч)) 100%
w3(C12H22O11) = (100g / 100g) 100%
w3(C12H22O11) = 100%

Therefore, the final weight percent of C12H22O11 in the solution is 100%.
