1. (LO 2) For each of the following dilutions, calculate the dilution factor between the original liquid and the final solution.
(a) 20 mL of solution Q is diluted to 100 mL.
(b) 500 ̀μ́L of solution X is diluted to 2.0 mL.
(c) 150 ̀μ́L of serum is added to 300 ̀μ́L of saline solution, and 20 ̀μ́L of the resulting solution is added to 180 ̀μ́L of saline solution.
(d) 25 mL of liquid W is diluted with solution Z to 75 mL and then to 750 mL with saline solution.
(e) 0.10 mL of plasma is diluted to 1.0 mL, and the resulting solution is brought to a final volume of 4.0 mL with diluent.
(f) 50 ̀μ́L of urine is added to 0.150 mL of water.
(g) 300 ̀μ́L of cerebrospinal fluid is added to 2.70 mL of diluent, and 0.50 mL of the resulting solution is added to 2.0 mL of saline solution.
(h) 5 mL of liquid K is added to 5.0 L of water.
(i) 10 ̀μ́L of urine is added to 90 ̀μ́L of diluent, and the resulting solution is brought to a final volume of 0.50 mL with water.
(j) 5 ̀μ́L of whole blood is pipetted into 1.0 mL of diluent.
(k) 0.040 mL of serum is added to 260 ̀μ́L of saline solution, and 150 ̀μ́L of the resulting solution is added to 1.35 mL of saline solution.
(l) 13 mL of solution M is brought to a final volume of 100 mL with solution N.
(m) 0.55 mL of plasma is mixed with 0.45 mL of diluent.
(n) 1.0 mL of saline solution is mixed with 0.50 mL of water.
