Question

1. There is 400 ul of saline in a test tube. 100ul of serum is added to the tube. Write in the correct format the following: a. Saline to serum ratio b. Serum to saline c. The dilution for the serum 2. If 500 ul of a solution contains 450 ul of diluent, how much sample is present? what is the dilution? 3. In a 1 to 10 dilution, what is the dilution factor? 4. If 0.25 parts of a sample are diluted into 4.75 parts of diluent, what is the dilution and dilution factor? 5. A 200 ul sample is needed to run a test. A 1/5 dilution needs to be made. How much sample and diluent is needed?
