A student takes 25.00 mL of a 5.00 M stock solution and adds it to a 50.00 mL volumetric flask. They dilute the stock solution with water and label it as Dilution #1. They then take another 25.00 mL of the stock solution and put it into a 50.00 mL volumetric flask and dilute it up to the line. They label this flask as Dilution #2. If the student uses the dilution equation (M₁ V₁ = M₂V₂) to calculate the final concentration of Dilution #2, what number should they set M₁ equal to? Select one: 5.00 M 2.50 M 1.25 M Cannot be determined from the information provided.
