If it is a mixture, then yes. Pure acetic acid is one hundred percent acetic acid, while vinegar is 5 or 10 percent acetic acid in water. You can make a solution of acetic acid and alcohol.

No, a sulfuric acid solution in water is homogeneous
mary mixed 2l of an 80% acid solution with 6l of a 20% acid solution. what was the percent of acid in the resulting mixture
10 liters.
Mixing 80 liters of 15% solution and 520 liters of 90% solution will give 600 liters of 80% solution.

7 liters of a 20% acid solution consists of 1.4 liters of acid (20% of the total volume) mixed with 5.6 liters of water (80% of the total volume). The amount of acid isn't going to change in the new solution. You are just going to add enough water to make it a 10% solution instead of a 20% solution. So it will be more dilute. That means that 1.4 liters of acid will represent 1/10 of the volume of the new solution. So the total volume of the new solution will be 10 x 1.4 or 14 liters. The amount of water in the new solution will be 14 - 1.4 = 12.6 liters. That is a difference of 12.6 - 5.6 = 7 liters from the amount of water you started with. So you need to add 7 liters of water to the original 20% solution to make it a 10% solution. This makes sense because if you double the amount of the mixture from 7 liters to 14 liters and the amount of acid is unchanged, the solution will be half as strong.
6 litres of 50% + 4 litres of 25%
Add 0,8 L of water.
