This is a serial dilution problem...

Explanation:

I don't what sodium cefotaxime is, and certainly I don't know its molar mass. Find its molar mass, and divide the mass by this quantity, and then provide the solution volume...

#"Molarity"="Moles of solute"/"Volume of solution"#

Here you prepare an initial concentration, and take a volume of this which contains a calculable number of sodium cefotaxime, and this is redissolved in another volume to give a FINAL, MORE DILUTE concentration. Anyway, I leave it up to you to provide the details.
