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.

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.
