You just ordered your cloning primers, and you have been tasked with re-suspending (aka. mixing into solution) the lyophilized (aka. Solid form) forward primer in water to a final concentration of 100 µM (remember, M = molarity NOT moles). The manufacturer specified the amount of primer produced at 27.5 nmol, with a molecular weight of your DNA primer at 8291.4 g/mol. Given this information, please calculate how much water you need to add to your primer tube (in µL) in order to achieve a final concentration of 100 µM. Please think this problem through first. Do not apply equations without thinking this through first. Please explain your answer (brief, point form) such that your TA can follow your rationale. Also, please show all mathematical steps
