Dilution Series for Liquid Culture of Staphylococcus Aureus
If you had a liquid culture of Staphylococcus aureus and transferred 2ml to test tube "R", which contains 8ml of nutrient broth, what would be the final dilution (in simplest terms) of the culture in test tube "R"? From the culture in "R" make a 1:15 dilution in tube "S". What is the final dilution of the culture in tube "S"?View Full Posting Details
