I have been provided with a stock solution of 17β-estradiol at 60 mg / L (solution A).
From this must be prepared 100 ml of solution B at a concentration of 60 g / L.
Question 1:
How many ul of solution A to be transferred?
Question 2:
What is the molarity of 17β-estradiol in the stock solutions A and B?

blues · Answer

Concentration 1 x Volume 1 = Concentration 2 x Volume 2

And you will need to look up (i.e., google) the molecular weight of 17-beta estradiol.
