Question

A "Bayer brand of aspirin was dissolved in some sodium hydroxide and transferred to a 100.0 ml volumetric flask and diluted to the mark with distilled water. A 2.2ml aliquot of this solution was transferred to a second 100.0 ml volumetric flask and diluted to the mark with iron (IIl) chloride solution. The concentration of the iron (II) salicylate complex was found to be 0.048mM. What was the original concentration of A.S.A (aspirin) in the original solution, in mM?

Answer 1

The numbers have changed since your first post below but the math process still is the same.
mM ASA in the original 100 mL volumetric flask will be
0.048 mM x (100 mL/2.2 mL) = ? mM.

Answer 2
