A stock solution was prepared by dissolving exactly 0.4000 g of pure ASA (180.16 g/mol)
in 10.00 mL of NaOH and heating the solution to a gentle boil. After cooling to room temperature, the solution was poured into a 250-mL volumetric flask and diluted to the mark with DI water. Before coming to lab, calculate the concentration of ASA in the flask.

None of the ASA is boiled away, presumably. Therefore you have 0.4000 g of ASA in 250 mL of liquid solution. With the molecular weight that was given, you can convert that to molarity (moles per liter)
