5 mL of standard aspirin solution (200ppm) is pipetted into a beaker and 1.5 mL of 0.5 M NaOH is added. The aspirin solution is then transfered into a 25-mL volumetric flask where 4 mL of 0.1 M Fe3+ solution is added to the flask. It is then diluted to the mark (25ml) with distilled water. What is the new concentration of the Asprin in mg/mL?

What is the final concentration of methyl red if:

A 0.05% solution of methyl red is prepared by dissolving 0.025 g in 20 mL of 95% ethanol in a 50- mL volumetric flask. Water is then added to within a few mL of the mark. ~0.1 M NaOH is added dropwise until all the solid dissolves and then diluted to the mark. 20 mL of this solution is then transfered into 50 mL of 95% ethanol in a 200 mL volumetric flask. This is then diluted to the mark with water.
