Need the answers to all please :) 1) You recently purchased a new mitogen at 1mg/1ml (stock) and then prepared 1:100 dilutions as a working solution (tube A). The company also suggest verifying the optimal dilution for your experiment by doing serial (twofold) dilutions. Describe how you would prepare 500microliters of working solution (tube A). What volume of inhibitor will you add in microliter? 2) You would like to optimize the working concentration of the inhibitor, and therefore perform two-fold...

19) prepare serial dilutions of a plant protein extract using sterile dH2O in a total volume of 100 microliters in each glass test tube. Tube 1-1/1 dilution, Tube 2- 1/2 dilution, Tube 3- 1/4 dilution, tube 4- 1/8 dilution, Tube 5- 1/16 dilution. (remember /= of) This says it does not have enough information, but this is a practice question i was given it must be solveable

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...

How do you find the initial concentration if you are only
given the initial volume and final volume? I have tried using the
V(i) x C(i) =V(f) x C(f) equation but it needs at least 3 figures
so I'm a bit lost right now.
