What is the dilution factor of the coffee if you start with 1 mL of coffee and 4 ml of water?
The dilution factor 1 mL coffee + 4 mL water = 1 mL coffee + 9mL water = 1 mL + 99mL water =Click to see full answer. Thereof, how do you dilute CFU mL?1. Take the amount you plated (0.5 mL) and multiply by the dilution factor (0.01) to yield 0.005. You must do…
The dilution factor 1 mL coffee + 4 mL water = 1 mL coffee + 9mL water = 1 mL + 99mL water =Click to see full answer. Thereof, how do you dilute CFU mL?1. Take the amount you plated (0.5 mL) and multiply by the dilution factor (0.01) to yield 0.005. You must do this to find the dilution factor which yielded your CFU count. Here, half a milliliter of the 1:100 dilution allowed you to count CFU.Furthermore, how do you dilute 50 times? Explanation: If you want to make a 1/50 dilution you add 1 volume part of the one to 49 parts of the other, to make up 50 parts in all. Thereof, how do I make a 1 100 dilution? For a 1:100 dilution, one part of the solution is mixed with 99 parts new solvent. Mixing 100 µL of a stock solution with 900 µL of water makes a 1:10 dilution. The final volume of the diluted sample is 1000 µL (1 mL), and the concentration is 1/10 that of the original solution.What is normal CFU mL?For that reason, up to 10,000 colonies of bacteria/ml are considered normal. Greater than 100,000 colonies/ml represents urinary tract infection. For counts between 10,000 and 100,000, the culutre is indeterminate. Sensitivity refers to the antibiotics tested to be effective in stopping the bacteria.
