Then you need to get a good book on enzymology and learn how to work this
out, it is not rocket science.
For example, if you release nitrophenol from p-nitrophenylphosphate by a
phosphatase, the determination is by photometry. The absorbance is related
to the concentration of NP (the product) by Lambert-Beer's law.
Concentration times volume gives amount, amount by time gives activity.
Activity divided by protein amount in the assay gives specific activity.
In your case I would recommend:
I.H. Segel: Biochemical Calculations, 2nd Ed. (Wiley) 1976, ISBN
Don't be confused by the age of this book, maths hasn't changed much in
the last 30 years!
