To answer this we need the Molarity of solution from part a. However, lets assume it is 0.1M
Formula to use:
M1 = 0.1 M
V1 = 2.0 lit
V2 = 2.0 + 1.5 = 3.5 lit
M2 = ?
= 0.1 * 2/3.5 = 0.057M
Dilution Formula. If you take 2.0 liters of solution from (a) and add 1.5 liters of...
7. THIS IS A DILUTION PROBLEM: You have 2.0 liters of a 6.0M HCl solution a) If 3 more liters of water are added, what will the b) If water is added to make a 1.0M solution, what will final concentration be? the final volume be?
-What is the molarity of 1.5 N CaCl2? -You take 1 mL of patient serum and add it to 3 mL of water. Next, you take 1 mL of the dilution you just made and add it to 4 mL of water. You perform a glucose test using this final sample and receive a result of 6 mg/dL. a. What is the dilution factor of the final sample? b. Is the patient’s glucose value in the reference range?
Dilution of Concentrated Solutions The number of moles of solute in liters of a solution of molarity is given by Moles Solute = m x v It is often of practical importance to take a concentrated solution of known concentration, and to add solvent to it to obtain a diluted solution with a desired concentration. During the process of dilution, since only solvent is added, the number of moles of solute is constant. Using to denote the concentrated solution, and...
Dilution, help??
5. You add 25uls of antibody to 475 uls of water - what dilution did you just make? 6. (3 pts) To obtain a countable plate to quantify your bacterial sample you first dilute the sample 1/500 in Tube 1 and then make a 1/25 dilution of this sample in Tube 2. If the total volume for your dilutions is 1 ml: a. How much water should be in Tube 1 and how much of your initial bacterial...
D 6. A solution of KOH has a Molarity of 1.5. How many liters of this solution would contain 3.0 moles of KOH? 0.22 L 4.5 L 2.0 L 3.0 L 0.50 L
You have a purified alcohol dehydrogenase from liver. You take 50 micro liters of this solution, and add 950 micro liters of buffer. The absorbance of the diluted solution is 0.542. A) what is the ADH concentration in the undiluted sample (in mg/ml)? The extinction coefficient for a 0.1% solution of ADH at 280 Bm is 1.83. B) what is the ADH concentration in micro M? (The molecular weight of ADH is 140,000 Da)
If I have 2 liters of a .250 M solution of NaCl and I add 500.0mL of water to it the number of moles will increase/decrease/remain the same and the molarity of the solution will increase/decrease/remain the same
