NOT: 15 ounces to make 10%
Correct answer:
Twenty ounces
Calculus:
Let it be M ounces. Then:
- 20%*(M ounce) + 5%*(40 ounce) = 10%*(M+40 ounce)
- 20*M + 200 = 10*M + 400
- (20-10)*M = 400-200
- 10M = 200
- M = 20

How much water must be added to a gallon of 10 percent saline solution to create a 2 percent solution?
There is 1 gallon of 10% solution...There is 0% saline in water...The equation is (0.1)(1) + 0x = 0.02 (x+1)...Answer is: 4 gallons. Hope I helped!!:)
What 0.18 percent saline mean?
Saline is basically water with common salt (Sodium Chloride) added. Therefore - 1 litre of saline has 0.18 percent salt.
How much water must be added to 1 liter of a 5 percent saline solution to get a 2 percent saline solution?
At dilution always true:Volume*concentration = amount of solute (= constant, not changing)So 1 (litre) * 5 (%) => 5
How much water added to convert a 10 percent solution to 02 percent solution?

A saline solution is formed.
How do you make a percent solution of saline for nasal irrigation?
A one percent saline solution (roughly isotonic) can be made by adding 1 teaspoon of salt to a litre of drinking water. The salt should not contain added iodine or anti-caking agents. Which means that kosher or pickling salt are appropriate but table salt isn't. The saline should be heated to a luke warm temperature before use.
How many ounces of pure water must be added to 50 ounces at a 15 percent saline solution to make a saline solution that is 10 percent salt?
Add 25 oz of pure waterLet X be the volume of pure water to add. Then the total amount of pure water you add plus the total amount of water in the 15% solution will equal the total amount of water in the final 10% solution.So,X + 50*(1-0.15) = (50 + X) * (1-0.10)X + 50*(0.85) = (50 + X)*(0.90)X + 42.5 = 45 + 0.90X1X - 0.90X = 45 - 42.50.10X = 2.5X = 25
What is the density of 40ml of saline solution in 50 ml beaker?
The density of 40ml of saline solution in a 50 ml beaker is 1.0046g/mL. The density will vary based upon the concentration of the salt added to the solution.
