Question: 21. A serial dilution is set up using 0.5 mL serum + 9.5 mL saline in the first tube. Tubes 2-5 each receive 2 ml

21. A serial dilution is set up using 0.5 mL
21. A serial dilution is set up using 0.5 mL serum + 9.5 mL saline in the first tube. Tubes 2-5 each receive 2 ml saline. If 1.0 mL of the tube #1 dilution is transferred to tube #2 and 1.0 mL of tube #2 dilution is transferred to tube #3 and the dilution is carried out in this manner for the remaining tubes, determine the final serum dilution of tube #5. 22. A serial dilution is set up using 0.5 serum + 0.5 ml saline in the first tube. Tubes 2-6 each receive 3 ml saline. If 1 ml from tube #1 is transferred to tube #2 and the dilution carried out in this manner, find the final serum dilution of tube #6. 23. A serial dilution is set up using 1.0 ml serum + 2.0 ml saline in the first tube. Tubes 2-5 each receive 0.8 ml saline. If 1.0 ml from tube #1 is transferred to tube #2 and the dilution carried out in this manner, find the final serum dilution of tube #5. 24. A serial dilution is set up using 1 ml serum + 9 ml saline in the first tube. Tubes 2-5 each receive 2.0 ml saline. If 2.0 ml from tube #1 is transferred to tube #2 and the dilution carried out in this manner, find the final serum dilution of tube #5
