Given information on the amounts that was used in order to create dilution Obtain 15.0 mL of 0.100 M CuSO4 solution in your 50 mL graduated cylinder. Using a prepared 10 mL volumetric pipet, dispense 10.00 mL of 0.100 M CuSO4 into a properly prepared 25 mL volumetric flask and dilute to the mark with distilled water. This is solution #1. Invert the volumetric flask 20 times to thoroughly mix the solution. Again using a prepared 10 mL pipet, transfer 10.00 mL of solution #1 to a second prepared 25 mL volumetric flask and dilute to the mark with distilled water. This is solution #2. Invert the flask 20 times. Using a prepared 10 mL pipet, transfer 10.00 mL of solution #2 to a third prepared 25 mL volumetric flask and dilute to the mark with distilled water. This is solution #3. Invert the flask 20 times. Using a prepared 10 mL pipet, transfer 10.00 mL of solution #3 to a fourth prepared 25 mL volumetric flask and dilute to the mark with distilled water. This is solution #4. Invert the flask
