A fictional cubed-shaped bacterium, Bacterius cubis, occupies a volume of 2.9 femtoliters. This particular type of bacteria is known to communicate with its own species by secreting a small molecule called bactoX (MW 1214 g/mol). A. Each bacterium contains 5530 bactoX molecules that can be secreted. How many moles of bactoX are present in a 1.0 L sample volume that contains 2.620 x 10" bacterial cells? moles: mol B. Calculate the molarity (mol/L.) of bacto X in the 1.0 ML...

1.Calculate the number of moles of avidin added for each titration based on the added volume of avidin stock solution and a MW of 68,000 g/mol. Conduct the following steps for each titration: 1) Add Vbuffer of 0.02 M sodium phosphate buffer, pH 7, to a disposable plastic cuvette. 2) Add Vavidin of a solution of 10 mg/mL avidin in 0.02 M sodium phosphate buffer, pH 7. Mix thoroughly by micropipetting up and down. 3) Put the cuvette in the...
