He should add 10 ml of the 15% solution.

You need 17 gallons for a 15% volume/volume mixture.
Let x = the amount of 20% solution Let x + 10 = the amount of the final solution. So we have: (.20)x + (.50)(10) = (.40)(x + 10) .20x + 5 = .40x + 4 .20x = 1 x = 5 liters of 20% solution of saline.
150 mlLet x be the volume of 20% solution to add. The amount of "stuff" dissolved in the 20% solution plus the amount in the 40% will equal the amount of "stuff" dissolved in the 25% solution.(0.20)(X) + (0.40)(50 ml) = (0.25)(X+50ml)0.2X + 20 = 0.25X + 12.520 - 12.5 = 0.25X - 0.20X7.5 = 0.05XX = 7.5/0.05 = 150 ml
10 liters.
To determine the amount of 18% solution to add: Let x = volume of 18% solution to be added. 0.18x + 0.10(360) = 0.15(x + 360) Solving for x, you would need to add 75 ml of the 18% solution to the 360 ml of 10% solution to obtain a 15% solution.
You would need to dilute the 0.1N HCl solution with distilled water in a 1:9 ratio (1 part HCl solution to 9 parts distilled water) once in order to obtain a 0.01N HCl solution.
Dissolve 15 g salt in 100 mL water.
To get details of samples quotations required by the company, one must first obtain a companys address. To obtain the address one can simply go to the companies page and hit contact. In contacting them one should be able to obtain that information.

You should take Multi-Vitamins and eat the required amounts of servings of each food groups every day.
To obtain a 12% alcohol solution, you would need to mix 12ml of alcohol with 48ml of water. This would give you a total volume of 60ml, with 12% of it being alcohol.
Approx 1.86 gallons.
Yes, you should be able to obtain borax solution from a chemist or a chemical supply store. It is often used in laboratory settings for various experiments and processes. Just be sure to check the purity and concentration of the solution to ensure it meets your specific needs.
