Answer is: distillation.
Solution of sugar and water has a uniform composition and is able to be separated by physical means.
Solution is homogeneous mixture has the same proporties of its components throughout any given sample.
Solution of water and salt, can be separated with distillation (process of heating and cooling). Water evaporates and sugar remain in the beaker.

Answer:
We have to add 14 mL of water to dilute the alcohol solution from 13% to 6%
Explanation:
Step 1: Data given
Original solution has 12 mL of 13% alcohol
New volume has a concentration of 6%
Step 2: Determine how much pure alcohol you have in the solution.
0.13 * 12ml = 1.56 ml pure alcohol.
Step 3: Calculate ratio alcohol: total in volume
1.56 ml / 12 ml = .013
Step 4: add water to the total solution and set the desired percentage
1.56 ml / (12ml + x) = 0.06
1.56 = 0.06 (12 + x)
1.56 = 0.72 + 0.06x
0.84 = 0.06x
x = 14
We have to add 14 mL of water to dilute the alcohol solution from 13% to 6%
