Question

Suppose you were instructed to add 0.2 mL of sample to 9.8 mL of diluent, but instead added 2.0 mL of sample. What was the intended dilution, and what was the actual dilution?

Answer 1

Intended dilution = 50 x; Actual dilution = 5.9 x

Step-by-step explanation:

Dilution factor = (Sample Volume + Diluent Volume)/Sample Volume

Intended dilution factor = (0.2 + 9.8)/0.2

= 50

Actual dilution factor = (2 + 9.8)/2

= 5.9

Answer 2

Intended dilution: 50 times

Actual dilution: 5.9 times

Step-by-step explanation:

Dilution: To decrease the concentration of the solute in a particular solution

Dilution= total volume of solution/volume of sample

Here, actual sample: 0.2ml, diluent: 2 ml

So, intended dilution= 10/0.2= 50 times

Actual sample: 2 ml

So, actual dilution=11.8/2= 5.9 times
