Why1.2 percent water solution of potassium chloride used in UV calibration?
The solution of potassium chloride is used to evaluate the stray light.
Weight of 6 percent KCL Pounds Per gallon?
The weight of 6% KCl (potassium chloride) solution is 6 pounds per gallon. This means that in one gallon of the solution, 6% of the weight is potassium chloride, which amounts to 6 pounds.
How many gallons of a 9 percent salt solution must be mixed with 25 gallons of a 31 percent solution to obtain a 20 percent solution?
25 gallons
How many gallons of 3 percent salt solution must be mixed with 50 gallons of 7 percent salt solution to obtain a 5 percent salt solution?
50 gallons @ 3% must be added.
How much 50 percent antifreeze solution and 40 percent antifreeze solution should be combined to give 50 gallons of 46 percent antifreeze solution?
How much 50 percent antifreeze solution and 40 percent antifreeze solution should be combined to give 50 gallons of 46 percent antifreeze solution?
How many pounds of calcium chloride would you add to 2000 gallons to make a 32 percent solution?
To make a 32% solution of calcium chloride in 2000 gallons, you would need to add 640 pounds of calcium chloride (2000 gallons is around 16666.7 pounds of water). This calculation is based on the percentage concentration formula: (amount of solute / total amount) * 100 = percentage concentration.
How do you dilute 500 gallons of 31 percent to 15 percent?
To dilute 500 gallons of a 31% solution to a 15% solution you would add 533.33 gallons of the dilutant. For example, if you have 500 gallons of a 31% saline solution you would add 533.33 gallons of water to create 1033.33 gallons of a 15% saline solution.
How many gallons of a 12 percent indicator solution must be mixed with a 20 percent indicator solution to get 10 gallons of a 14 percent solution?
Let x represent the amount of 12% solution and (10-x) represent the amount of 20% solution. The equation to solve is: 0.12x + 0.20(10-x) = 0.14(10). Solving for x gives x = 4, so you need 4 gallons of the 12% solution and 6 gallons of the 20% solution to make 10 gallons of the 14% solution.
Why is sodium chloride 0.9 percent percent given?
This is a isotonic saline solution.
Which has the highest conductivity between sodium chloride crystal and 5 percent sodium chloride solution?
The solution being an electrolyte is electrically conductive.
How many gallons of a 80 percent solution must mix with 70 gallons of 10 percent solution to get 70 percent solution?
420 gallons. Here's how to find it; If X = Gallons of 80% mix, 0.8*X + 0.1*70 = 0.7*(X+70) Which we can then solve, 0.8X + 7 = 0.7X + 49 0.1X = 42 X = 420
How many gallons of a 50 percent antifreeze solution must be mixed with 70 gallons of 30 percent antifreeze to get a mixture that is 40 percent antifreeze?
70gallons
