Pour 2.5 mL of the 1M glucose (C6H12O6) solution from the flask into the 100 mL volumetric flask. Use the “dilution equation” to determine the volume in mL for the required 0.025M solution, given that the original solution is 1M and you used 2.5 mL Fill the volumetric flask to the 100 mL mark with distilled water. Note: The flask already contains a volume of 2.5 mL. 1. Compute the volume of the diluted 0.025 M solution. 2. What volume...

2. A stock solution of 1.24 x 10^-4 M dye is available in the laboratory. What volume of the stock solution must be transferred to the volumetric flask to prepare a 25.00 mL dilution with a concentration of 2.00 x 10^-5 M? 3. Perhaps the volume in question 2 is an inconvenient fractional amount. What volume should the analyst dispense to simplify the preparation of the dilution?
