What is the volume of 0.25M PMSF & volume of 14.3M 2-mercaptoethanol needed in 25 mL of 20 mM sodium phosphate?

MW of sodium sulfate = 137.99

• chem -

What, pray tell, is PMSF. And what is the question?

• chem -

it's just a solution.

I'm not sure how to find the volume dilution... this is a dilution problem.
