Topic: Serial dilution quiz You have an original cell density of 2.10 x 107 CFU/mL. What is this number in its non-scientific notation or “regular” format? If you’ve taken 500 ul of a bacterial culture and added 500 ul of DI water, you have achieved what dilution (i.e. what is the dilution factor)? Group of […]
Prepare the 3 standards in 100 mL volumetric flasks using distilled water as diluent at concentrations of 1.0, 5.0, and 10.0 mg/L. Calculate the volumes needed to prepare them first.
DETERMINATION OF FLUORIDE USING AN ION-SELECTIVE ELECTRODE PURPOSE This experiment is designed as a no-risk opportunity to demonstrate competence in calculations and performing the associated dilutions to create a calibration curve with high linearity and high accuracy (as determined by the slope of a linear regression between instrument response vs concentration). You will then apply […]
