10ml of ethanol mix with 40ml of water find percent concentration of ethanol solution?
The total volume of the solution is 10ml + 40ml = 50ml. The percentage concentration of ethanol in the solution is (10ml / 50ml) * 100% = 20%.
What is the volume of 75.0g of ethanol?
The volume of 75.0g of ethanol can be calculated using the density of ethanol, which is about 0.789 g/mL at 20°C. By dividing the mass by the density, we find that the volume would be approximately 95.1 mL.
How is the solubility of Tween 20 in ethanol?
Tween 20 is soluble in ethanol, making it a suitable choice for formulations requiring a non-ionic surfactant that can be dissolved in ethanol. The solubility of Tween 20 in ethanol allows for its use in various applications such as pharmaceuticals, cosmetics, and food products where ethanol compatibility is needed.
What happens to the volume when you mix water and alcohol together?
Well I tried this yesterday. I had an 80/20 water/IPA mix. The water went milky and there was a foam on top of the water. The effectiveness of the IPA was diluted as well. I use it as a solvent and it was not effective at this concentration.
Can you make 10 volume developer out of 20?
To make 10 volume developer from 20 volume developer, you can mix equal parts of 20 volume developer and distilled water. For example, mix 1 part of 20 volume developer with 1 part distilled water to create 10 volume developer.
10ml of ethanol mix with 40ml of water find percent concentration of ethanol solution?
The total volume of the solution is 10ml + 40ml = 50ml. The percentage concentration of ethanol in the solution is (10ml / 50ml) * 100% = 20%.

How to prepare 20% (v/v) of ethanol?
To prepare a 20% (v/v) solution of ethanol, you need to mix 20 mL of pure ethanol with enough solvent to make a total volume of 100 mL. This means that for every 100 mL of solution, there are 20 mL of ethanol. You can use a volumetric flask to accurately measure the volume of the ethanol and the solvent. It is important to note that the volume of the final solution may not be exactly 100 mL due to the fact that liquid volumes are not necessarily additive.
How is the solubility of Tween 20 in ethanol?
Tween 20 is soluble in ethanol, making it a suitable choice for formulations requiring a non-ionic surfactant that can be dissolved in ethanol. The solubility of Tween 20 in ethanol allows for its use in various applications such as pharmaceuticals, cosmetics, and food products where ethanol compatibility is needed.
How much 10 volume cream developer do you mix with 40 volume cream developer to make 20 volume?
Mixing 10 Volume developer and 40 volume developer will never make a 20 volume regardless of how much is mixed. In order to make a 20 volume, equal parts of 10 and 30 volumes will need to be mixed. Mixing 10 and 40 will make 30 volume.
Do 10 an 30 developer make 20?
Yes, if mixed equally, a 10V + 30V= 20 Volume developer.
What happens to the volume when you mix water and alcohol together?

How do you make 10 volume from 20 volume?
To make a 10 volume solution from a 20 volume solution, you need to dilute the 20 volume solution with an equal amount of water. For example, mix one part of the 20 volume solution with one part of water. This will effectively halve the concentration, resulting in a 10 volume solution.
What is the resulting density when 20 milliliter of ethanol is mixed with 100 milliliter of ethylene glycol?
Multiply each by their densitiesget their summationdivide the summation by 120
What volume of developer do you use on beards?
A 20 volume developer will be sufficient for coloring facial hair, especially if there are some grays mixed in.
How do you find the volume of 15 grams of ethanol?
Ethanol (USP grade) has a density of 0.810. From here we have to use the formula: d=m/v, where d is density, m, mass and v, volume. Solving for volume, we have v=m/d, therefore: v= 15/0.810 = 18.52 mL of ethanol are equivalent to 15g.
How long do you leave on redken nw color gel on hair to process?
Redken Color Gels Processing is as follows: Mixed with 10 volume developer: Process 20 mins. at room temp. Mixed with 20 volume developer: Process 30 mins. at room temp. Mixed with 30 volume developer: Process 40 mins. at room temp. Mixed with 40 volume developer: Process 45 mins. at room temp. It's the DEVELOPERthat determines the processing time, not the color.
