Seven Tubes Contain 1 ml of Saline. You add 1 ml of a 64 mg/ml sample in tube 1. From tube 1 you take 1 ml and add it to tube 2. From Tube 2 you take 1 ml and add it to tube 3. You repeat this through tube 7. Write the sample concentration in each tube?
Homework Answers
In each tube 1 ml of saline is present, now if we add 1ml of 64mg/ml sample in the tube 1 then it is diluted 1:2 times and the concentration is reduced to half that is 32 mg/ml in tube 1.Similarly in the rest of the tubes the concentration will be as follows.

phenol is in each of your unknowns. 1. You will be given a nitrophenol solution of concentration 400 nmoles/mL and you will use this stock solution to make a serial dilution as follows: To make the serial dilution you need to prepare 5 tubes with 1 ml water. Next, add 1ml from the 400 nmoles/ml stock to the first tube. Pipette the solution up and down carefully and remove 1 ml of this solution to the next tube. Repeat this...
