suppose you are preparing a solution for a kinetic experiment when given a stock concentration 0.002M. your mixing 200 ul +30 uL+ 60 ul and your trying to find final concentration of the solution
0.002M. your mixing 200 ul of 0.002 m+30 uL of 0.002 M + 60 ul of 0.002M solution so the concentration will remain same
if you mention the stock volume and the dilution u want know
we can use m1v1 = m2v2
say m1 = 0.002M
v1 = amout of stock solution nedded to add a solution to get a desired concentration of solution
M2 = required concentration
V2 = volume of required concentration

If you wanted to dilute this solution to make a total of 1 ml of a 3 mM solution, what volume of stock and what volume of water would you use? Give your answer in microliters (ul), and show your calculations. Volume of stock3 ul Volume of water · T ul
Suppose you made the intestinal sac too small, and at the end of experiment you could collect only 100 microliters of solution instead of 200 microliters for analysis. You perform the DNS reaction with 100 ul of the recovered solution and 100 ul of water (to bring volume up to 200 ul). How that would affect the concentration of glucose you determined from the standard curve? Normal Experiment 200 ul solution 200 ul of DNS 400 ul of H2O A)Half...
You are given a stock solution of ribosylated collagen. In order to complete your experiment, you will need four 1ml aliquots of ribosylated collagen in phosphate buffered saline (1M), each containing 67.5 ng/ml. The stock concentration is 10 ug/ml, What steps are required to achieve the required concentrations? During lab a classmate accidentally breaks an Erlenmeyer flask: a single shard causes a 50mm laceration between his elbow and wrist. You decide that the best way to keep the wound clean...

Make an additional 200 mL of 15% sucrose solution in Beaker 1 by mixing the 30% stock solution with water. Use the following dilution equation to solve for the necessary amount of stock solution MV, = M2V2 Where: • V1 = Needed volume of stock solution M =...
One component of the Minimum Inhibitory Concentration experiment is the creation of an antibiotic serial dilution. In this assignment, you are to determine the appropriate dilution from the original stock needed to reach the final concentration of antibiotic in 1 mL of media. In your experiment, you are to add only 10 mu L of antibiotic to the media. You are given the starting concentration of the antibiotic (the stock solution) and the final concentrations needed. The first three answers...
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...
