How many ounces of 20 percent saline solution must be added to 40 ounces of a 5 percent saline solution to make a 10 percent saline solution?
NOT: 15 ounces to make 10%Correct answer:Twenty ouncesCalculus: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 = 400-20010M = 200M = 20
How many liters of a 20 percent solution of saline should a nurse mix with 10 liters of a 50 percent solution to obtain a mixture that is 40 percent saline?
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.
What happens to a fresh water organism in 20 percent of saline solution?
it dies since it enters a hypotonic solution thus making it shrink
Is normal saline with 20 percent kcl a hypertonic solution?
Yes, a solution of normal saline with 20% KCl would be considered hypertonic because it has a higher osmolarity compared to normal body fluids. This means that it will exert an osmotic pressure that can cause water to move out of cells and potentially cause cellular dehydration.
A pharmacist mixed a 20 percent solution with a 30 percent solution to obtain 100 liters of a 24 percent solution How much of the 20 percent solution did the pharmacist use in the mixture?

If you have an order for 20 percent dextrose 500 ml you have 1000 ml bag of dextrose 70 percent how much of the dextrose 70 percent do you need to use to make dextrose 20 percent 500 ml?
To make a 20% dextrose solution, you need to dilute the 70% dextrose solution with water. You need to use 178.57 ml of the 70% dextrose and 321.43 ml of water to make 500 ml of 20% dextrose solution.
How do you make 50 percent to 20 percent solution?
To make a 50% solution from a 20% solution, you need to concentrate the solution by evaporating some of the solvent. This will increase the concentration of the solute in the solution, making it 50%. Keep in mind this process should be done carefully, as it can be hazardous.
How much salt must be added to 60kg of a 20 percent solution of salt to increase it to 40 percent solution of salt?
20%
How many milliliter of a 20 percent and a 65 percent solutions should you mix together to make 500 milliliter of a 45 percent solution?
Let x be the amount of the 20% solution and y be the amount of the 65% solution. The total volume equation is: x + y = 500. The total amount of the solute equation is: 0.20x + 0.65y = 0.45(500). Solve these two equations to find the amounts of each solution needed.
How do you make 10 percent solution from 20 percent solution?
To make a 10% solution from a 20% solution, you can mix equal volumes of the 20% solution with water. For example, to make 1 liter of 10% solution, mix 500 ml of the 20% solution with 500 ml of water.
