1. You are given 15 ml of a 45% solution and told to add (not dilute to) 175 ml. What will the final strength of the diluted solution be?
2. You need to make a 10% solution using 4 ml of a 70% stock solution. How much sterile saline do you need to add to make this product?
3. You are given 5 ml of a 65% solution. If you dilute the solution to make a 15% solution, what is the volume of the final solution?

Please help with solving these problems I am having a hard time trying to work them out 1. You need to make a 15% solution using 25 ml of a 80 % stock solution. How much sterile saline do you need to add to make this product? Round your answer to one decimal place (tenths), where appropriate. 2. Your are given 25 ml of a 80% solution and told to add (not dilute to) 275 ml. What will the final...
11. Congratulations, you are a nurse in a neonatal intensive care unit (NICU)! In this unit many antibiotics need to be diluted before being given because of the low body weight of infants. In order to treat a newborn with bacterial sepsis (i.e., infection of the blood) you are told to prepare an antibiotic solution. You are given a bottle that contains 7.91 ml of sterile saline and a bottle that contains 12 ml of an antibiotic solution and are...
answering the following problems, state the volume of the given concentrate to be used au the volume of the diluent to be added and the final volume and diluted strength of the d solution. 20. Zephran chloride antiseptic is available in 16% concentration. How many ml ofthis concentration are needed to prepare 600 ml of0.2% solution? 21. How many liters of a 1:500 solution do you need to prepare 4 liters of a 1:800 solution? 22. Concentrated sodium of has...
If you dilute 17.0 mL of the stock solution to a final volume of 0.260 L , what will be the concentration of the diluted solution?
Question 1: In the laboratory you dilute 3.33 mL of a concentrated 6.00 M hydrochloric acid solution to a total volume of 75.0 mL. What is the concentration of the dilute solution? M Question 2: You wish to make a 0.153 M hydroiodic acid solution from a stock solution of 3.00 M hydroiodic acid. How much concentrated acid must you add to obtain a total volume of 100 mL of the dilute solution? mL Thank-you!
How do you work this problem? You have 5 ml of a 75% solution. You dilute the solution to 50 ml. what is the new percent strength of the diluted solution?
You need 100 mL of a 0.00057 M solution for an experiment. You are given 10 mL of a 5.7 M stock solution. What is the best method to get the final volume and concentration you for trial? -It is not possible to reach that concentration with the info presented. -Use a 1.0 mL volumetric pipette and then dilute with water to 100 mL, then repeat serially until the desired concentration is reached. -Use a graduated cylinder to measure 0.1...
You have a 1 M solution of NaCl. How much do you need to dilute to make 10 L of isotonic saline (0.9%)? Remember that the units of volume and concentration must be the same on both sides of the equation.
please show work so: 1 ml stock 10 ml final -0.5 mL of stock -5 ml final volume While I have used 1:10 as a standard the same rules apply for all dilution factors. Try these problems: x 0.5 X0.5 1. You need to make a 1:25 dilution factor. If you final volume is 25 mL this means that you need_ _mL of stock and mL of solvent to make your final volume of 25 mL. 2. If you needed...
