I am having much difficulty with this problem, partly because the wording is a little tricky.. if anyone could offer some insight it would be greatly appreciated!

You are given a stock solution of ribosylated collagen. In order to complete your experiment, you will need four 1ml aliquots (portions) of ribosylated collagen in phosphate buffered saline (1 M), each containing 67.5 ng/ml. The stock concentration is 10 (micro)grams/mL. What steps are required to achieve the required concentrations?

C1V1=C2V2

(10ug/mL)V1=(67.5ng/mL)(4mL)

V1 is the volume of stock solution that you need to mix with PBS to bring the total volume to 4mL.

I graduated from Bunker Hill Community College. Get on my level.

Well here's a way to get some work out of all the built up neurotic pre-meds on SDN. Good strategy, OP.
