You have 0.3 mL of an undiluted culture and add it to 2.7 mL sterile diluent. What is the dilution now? You have a 3 mL sample and you want to make a 1/100 dilution. How many mL of sterile broth should you add to the sample? You take a 2 mL sample of water you suspect is contaminated. You take 1 mL of your solution and place it in 9 mL of sterile broth. What is the dilution concentration?

Step 1
For the first question, we have 0.3 mL of undiluted culture added to 2.7 mL of sterile diluent. To find the dilution, we can use the formula: Dilution = (Volume of undiluted culture) / (Total volume) Dilution = (0.3 mL) / (0.3 mL + 2.7 mL) Dilution = 0.3 / Show more…

If you diluted a solution of molecules by putting 300 uL into 2.7 mL of water, mixing, and taking 300 uL from this dilution into another 2.7 mL of water, what is the dilution in the final tube? 1/10,000 1/100 1/100,000 1/1000
