A sample of pure acetyl salicylic acid had a mass of 0.268 grams. It was dissolved in NaOH and diluted to 500.00 mL in a volumetric flask. What is the concentration of aspirin in the solution?  If an 8.00mL sample of this solution was pipetted into a volumetric flask and diluted to 100.00mL, what is the concentration of aspirin after this dilution?
