Expert Solution
Step 1
Hello, thank you for the question. I am answering the first two questions, please repost the remaining questions.
The concentration of a particular sample can be determined using the optical density method. The lesser the dense sample is, the less light will be scattered in the sample, and the lesser will be the absorbance. The sample with a higher density of cells have more optical density and vice versa
