known to communicate with its own species by secreting a small molecule called bactoX (MW = 113.7 g/mol). A. Each bacterium contains 5140 bactoX molecules that can be secreted. How many moles of bactoX are present in a 1.9 µL sample volume that contains 4.444 x 10° bacterial cells? moles: mol B. Calculate the molarity (mol/L) of bactoX in the 1.9 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.
