describe how would you prepare exactly 500. ml of 1.0 M NaOH solution from a 3.0 stock NaOH solution . show all calculation
3.0 WHAT stock NaOH solution? Do you mean molar?
Use mL x M = mL x M.
After calculating mL of the stock solution needed, transfer exactly xx mL stock solution to a 500 mL volumetric flask, then add distilled /(deionized)/(DI) water to the mark in the neck of the volumetric flask.
