How many liters of water must be added to 7 liters of a 20 percent acid solution to obtain a 10 percent acid 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.
When a discount is 10 percent is given on on an item being sold at a profit of 20 percent on the cost price the sales volume trebles what is the ratio of new profit to original profit?

What developers do you mix to get 30 volume?
To achieve a 30 volume developer solution, you can mix equal parts of a 20 volume developer and a 40 volume developer. This will result in a 30 volume developer solution.
How do you dilute 20 volume developer to 10vol?
To dilute 20 volume developer to 10 volume, mix equal parts of 20 volume developer and a neutral liquid, such as distilled water or a low-volume developer. This will reduce the concentration of the developer and create a 10 volume solution for gentler hair processing. It's important to measure accurately to ensure the desired volume is achieved.
I have cream peroxide developer 10 but the hair color i have calls for creme peroxide developer 20 can i double developer 10 and it work like developer 20?
It is not recommended to double the volume of developer to achieve the desired strength. Using a 10-volume developer when a 20-volume developer is needed can result in uneven hair color or ineffective processing. It is best to use the correct developer volume for the hair color you are using.
What happens if you mix 1 oz of 20 volume and 1oz of 10 volume developer to hair color?
