A fictional cubed-shaped bacterium, Bacterius cubis, occupies a volume of 2.8 femtoliters. This particular type of bacteria is known to communicate with its own species by secreting a small molecule called bactoX (MW = 122.4 g/mol). A. Each bacterium contains 8850 bactoX molecules that can be secreted. How many moles of bactoX are present in a 1.2 µL sample volume that contains 3.234 × 10° bacterial cells? 4.75 x10-18 moles: mol Incorrect B. Calculate the molarity (mol/L) of bactoX in the 1.2 µL sample volume if all of the bacteria were to simultaneously secrete all of the bactoX molecules contained within their cell bodies into the vial. 3.96 x10¬12 concentration: M Incorrect
