Whatever method of mixing is used, geometric dilution is intended to do which of the following? (Choose ONLY two) I have to fill in this spot b/c Blackboard wont let me leave it blank. This is obviously not an answer to select, so if you do, I will think less of you and so will your future boss since you cannot follow directions. To ensure uniform particle size when the drug and the diluent are of different texture To ensure uniform mixing when the drug and diluent are indistinguishable and you can’t tell visually that they are well mixed To ensure uniform distribution when a small amount of potent API is to be mixed with a large amount of diluent

Which of the following describes the meaning of geometric dilution? A. Dilution by the addition of diluent in aliquots that are double the amount to be diluted B. Dilution by the addition of diluent in aliquots equal to the amount to be diluted C. Mixing ingredients in aliquots that are squared each time D. All of these are good descriptions, so this is the answer

A student performed a serial dilution involving a 1.00 mol dm–3 solution of NaCl. To do this, the student took 10 cm3 of that solution, added it to a 100 cm3 volumetric flask and diluted with water up to 100 cm3 to create dilution #1. The student then took 10 cm3 of dilution #1, added it to a 100 cm3 volumetric flask and diluted with water up to 100 cm3 to create dilution #2. The student repeated this process 3 more times to get dilution #5.Calculate the concentration of dilution #5 in g cm–3.

If you add 1.0 ml of a colored solution (Stock) to 4.0 ml of water in a test tube, what is the dilution ratio, of the colored solution to the final volume?

A bacterial stock solution was found to have a density 5.0 x 106 cells. The microbiologist took 1 mL of the stock solution and diluted it to a final volume of 10 mL with the appropriate media. Which of the following statement regarding the dilution is true?

How would you make a 10x sample dilution to a total volume of 1 ml?
